Bayrol Automatic Chlorine pH Dosing System – Laboratory Precision for Your Pool

No more guesswork. No more reading test strips at dusk. No more fear that the pool will "turn over" after a hot weekend with 20 guests.

You know the drill: test strips in the water. pH at 7.8 – too high. Chlorine at 0.4 mg/l – much too low. You calculate. Dose. Wait 6 hours. Measure again. Now pH at 7.1 – too low. Chlorine at 1.2 – too high. And all the while, the uncertainty: "Is the water really safe now?"

With Bayrol Automatic Chlor pH, this gamble is over.

The intelligent liquid dosing system, featuring German precision engineering, continuously measures pH and redox values ​​(chlorine content) – not just once a day, but every second. As soon as a deviation is detected, it automatically doses: liquid pH reducer and liquid chlorine. Pinpoint accuracy. Laboratory precision. Without any intervention from you.

The large 4.3" touchscreen display shows you at a glance: pH 7.2 – perfect. Redox 720 mV – optimal. Temperature 25°C. Everything's in the green – while you're standing at the grill, not in the utility room with measuring cups and canisters.

What makes it special : The Automatic Chlor pH uses liquid chemicals instead of tablets or granules. Why? Because liquid is the purest, most precise, and fastest-acting form of dosing. No dissolving time. No cyanuric acid buildup (as with multi-tabs). Instead: Immediate, even distribution in the water.

Recommended as a complete set with Smart&Easy Connector (transparent inline chamber for easy installation), 2x Level Kit (automatic level monitoring of the canisters) and Temperature Kit (water temperature display on screen + app).

Made in Germany. With WiFi module for app control. For all pool sizes. With quiet peristaltic pumps (2.4 l/h flow rate).

This isn't just any dosing system. This is your digital pool butler with lab-developed DNA.

The 5 most important advantages at a glance:

• Continuous real-time measurement instead of daily measurement : Measures pH and redox every second (not once a day like with test strips) – detects deviations immediately and corrects before problems arise.
• Liquid chemicals for immediate effect without waiting time : Chlori liquids + pH reducer liquid distribute evenly in water immediately – no dissolving time like with tablets, no cyanuric acid build-up like with multi-tabs.
• Precise dosing saves up to 40% on chemicals : Adaptive proportional control doses exactly the missing milligram – no overdosing, no waste, lower operating costs than manual dosing
• WiFi remote control + fill level monitoring : Control via app even from vacation, push notifications in case of deviations, automatic warning "pH canister only 20% full"
• Made in Germany with peristaltic pumps : German Bayrol quality since 1927, low-noise precision pumps (1.5 bar delivery pressure), IP65 splash-proof, built for decades of reliability

For whom is this dosing system ideally suited?

The reality check : The Automatic Chlor pH is for people who understand that precise water values ​​are not "nice to have", but essential – for health, comfort and maintaining the value of the pool system.

✓ Perfectionists with a need for control
You're an engineer, a tradesperson, or work in a profession where precision is paramount. Test strips with their approximate color scale frustrate you. You want exact numbers: pH 7.23 (not "somewhere between 7.2 and 7.4"). The Automatic Chlor pH measures with laboratory sensor accuracy – you see the exact number on the display, not a color estimate.

✓ People who have once had the "pool tipped over after heat" nightmare
Last summer: 3 days of 35°C, the kids in the pool for 5 hours every day, friends over on the weekend. On Monday, the water was cloudy, slightly greenish. The chlorine level was too low; the manual dosing couldn't keep up. This wouldn't have happened with the Automatic Chlorine pH system: it would have automatically added more chlorine when the pool was busy – without you even noticing.

✓ Technical traditionalists who trust liquid chlorine
You've been using liquid chlorine (sodium hypochlorite 13-15%) for years. You know it's the purest form – no fillers, no cyanuric acid, immediate effect. But manual dosing is a hassle. The Automatic Chlor pH automates your tried-and-tested method – you keep liquid chlorine, but gain automation.

✓ Smart home enthusiasts with digital control
You have Philips Hue, Nest, smart garden irrigation. Your pool is the next upgrade. The Automatic Chlorine pH with WiFi, app, and real-time monitoring integrates seamlessly. You want to see from your Apple Watch: "Pool status: Optimal" – not have to read test strips like in 1985.

✓ Busy people who don't have time for "Chemist Saturdays"
You work 50+ hours a week, and on weekends you want to enjoy your pool – not adjust pH levels. The Automatic Chlorine pH takes care of everything: measuring, analyzing, and dosing. You open the app, see "everything green" – done. No more 30-minute measuring and dosing ritual.

✓ People who hate handling chemicals
Chlorine tablets create dust when opened. Granules spill. You find handling chemicals unpleasant and old-fashioned. The Automatic Chlor pH meter doses from closed canisters – you don't touch or smell any chemicals. Clean hands, clean water.

✓ Pool owners with expensive equipment (liner, heat pump, counter-current system)
Your pool has a €2,000 liner and an €8,000 heat pump. Incorrect pH levels (too acidic or too alkaline) damage the materials – leading to corrosion, liner fading, and a shortened lifespan. The Automatic Chlorine pH system keeps the pH level stable at 7.2 ±0.1 – protecting your investment.

✓ People who distrust salt electrolysis
They have concerns: Salt could corrode stainless steel parts (ladders, counter-current system). Or: Electrolysis works less effectively at a water temperature of 30°C. They prefer the tried-and-tested, immediately effective liquid chlorine method – but automated.

✓ Pool owners with varying bathing loads
Sometimes you use the pool alone (low chlorine consumption). Sometimes 15 people come for a barbecue (high chlorine consumption). The Automatic Chlorine pH adjusts automatically: it doses more chlorine when there's a high volume of swimmers, and less when there's a low volume – always optimal, never wasteful.

Product description: Where precision meets automation

The end of the "test strip lottery"

Imagine this: You wake up Saturday morning. In the past, you would have had to go to the pool – test strip in the water, wait 15 seconds, compare the colors, guess: "Is this 7.2 or 7.4?" Today? You open the Bayrol app on your smartphone. One glance. pH 7.22. Redox 730 mV. Temperature 24.5°C. The Automatic Chlorine pH has kept everything perfectly balanced overnight.

This is not a vision of the future. This is your new pool reality from the moment it's installed.

Liquid chemistry – The professional method

The Bayrol Automatic Chlor pH uses two liquid chemicals:

1. Chloriliquid (sodium hypochlorite 13-15%):
The purest form of chlorine. No fillers, no stabilizers, no cyanuric acid (which accumulates in multi-tabs and eventually blocks the chlorine's effectiveness). Chloriliquide works instantly – it's distributed and disinfected in the water within minutes.

2. pH-Minus Liquid Domestic (38% sulfuric acid or hydrochloric acid):
Lowers the pH value precisely and quickly. The liquid distributes evenly in the water – no dissolving time like with pH-minus granules.

Why liquid is better than tablets/granules:

Immediate effect : Tablets take 6-12 hours to dissolve. Granules 2-4 hours. Liquid works in minutes.

Even distribution : Tablets lie on the bottom and dissolve locally (high chlorine concentration in one spot). The liquid spreads evenly immediately.

No cyanuric acid buildup : Multi-tabs contain a stabilizer (cyanuric acid) that accumulates in the water. At concentrations of 80-100 mg/l, it blocks the effectiveness of chlorine – the water will not become clean despite the addition of chlorine. Chloriliquide does not contain cyanuric acid.

Precise dosing : With tablets, you dose in 200g increments (one tablet). With liquid, the pump doses exactly 5ml, 10ml, 50ml – whatever is needed.

Continuous real-time measurement – ​​the core of the system

The Automatic Chlor pH does not measure once a day (as you would with test strips), but continuously:

pH sensor (single-rod measuring chain, BNC connector):
Measuring range 0-10.0 pH. Measures every second. Calibration with pH 7 buffer solution (included).

Redox sensor (single-rod measuring chain, BNC connector):
Measuring range 0-999 mV. Measures the oxidizing power of the water = indirect measure of the chlorine content. Target value: 700-750 mV = optimal disinfection. Calibration with buffer solution 465 mV (included).

Temperature sensor (optional, included in the complete set):
Measures water temperature. Important because chlorine effectiveness is temperature-dependent (chlorine is consumed faster at 30°C than at 20°C).

Flow sensor (optional, included in the Smart&Easy Connector):
Safety: Measurement and dosing only with the filter pump running. Prevents incorrect dosing.

The result : The system knows exactly what is happening in the pool at all times – and reacts immediately to deviations.

Adaptive Proportional Control – Intelligent Dosing

The Automatic Chlor pH does not dose according to the motto "more is better", but intelligently:

Small deviation (pH 7.3 instead of 7.2):
→ Small dose (10ml pH Minus), wait, measure, done.

Large deviation (pH 7.8 instead of 7.2):
→ Several medium doses (50ml, wait, measure, another 50ml, wait, measure) until target value is reached.

This prevents :

• Overdose (because 200ml cannot be pumped "all at once")
• Fluctuations (because corrections are made gradually)
• Chemical waste (because only what is actually needed is dosed)

Practical example : Manually, you might add 150ml of pH reducer to the water at pH 7.6 – and find 6 hours later that the pH is now at 7.0 (too low). The automatic system would have dosed 80ml, waited, measured, and then dosed another 30ml – final result: pH 7.2. Perfect.

Low-noise peristaltic pumps – precision without noise

Two peristaltic pumps (one for pH minus, one for chlorine liquids) dose the chemicals:

Flow rate : 2.4 l/h per pump (max.)
Delivery pressure : 1.5 bar (sufficient for feeding into pressure line)
Operating principle : Peristalsis = a rotor compresses a hose, pushing the liquid forward. No contact between the pump and the chemical (only the hose is in contact) → long service life, no corrosion.

Low noise : The pumps are barely audible (a quiet hum). No loud clacking like with cheap diaphragm pumps.

Precise : The delivery volume is exactly adjustable – from minimum quantities (0.1 l/h) to maximum output (2.4 l/h).

Smart&Easy Connector – The all-in-one inline chamber (optional)

The Smart&Easy Connector (included in the complete set) is a transparent inline dosing and analysis chamber that is installed in the pool piping (after pump and filter, before return nozzles).

What's inside:

• Sensor holder for pH sensor and redox sensor (the water flows past the sensors)
• Injection valves for pH reduction and liquid chloride injection (the chemical is dosed directly into the flowing water)
• Flow switch (only enables measurement/dosing when the pump is running)

Advantages :

• Easy installation : All components in one chamber – no need to install them individually in different pipes.
• Transparency : You can see if water is flowing, if the sensors are clean.
• Safety : Flow switch prevents incorrect dosing when the pump is stationary.

Ø63 and Ø50 connectors included – fits standard pool piping.

Level Kit – Automatic level monitoring

Included in the complete set: 2x suction lances with fill level sensor.

How it works : The suction lance is inserted into the canister (10L or 20L canister). A sensor continuously measures the liquid level.

Display on screen + app :

• "pH canister 80% full" (green icon)
• "Chlorine canister 30% full" (yellow icon + warning "Empty in 2 weeks")
• "pH canister empty!" (red icon + alarm)

Advantage : You know in advance when you need to reorder. No unpleasant surprise: "Oops, the pH canister is empty and the system hasn't been dosing for 3 days."

Temperature kit – water temperature at a glance

Included in the complete set: temperature sensor for integration into the Smart&Easy Connector.

Why is it important?
The effectiveness of chlorine is temperature-dependent. At 30°C, chlorine is consumed faster than at 20°C. The system can adjust the dosage accordingly (automatically dosing slightly more chlorine at higher temperatures).

Display : The current water temperature (e.g. 24.5°C) can be seen on the display and in the app.

4.3" touchscreen with intuitive operation

Large 4.3" TFT color touchscreen – just like a smartphone. No buttons, no dials. Swipe, tap, done.

Main screen displays :

• Current pH value (e.g. 7.22)
• Target pH value (e.g. 7.20)
• Current redox value (e.g. 730 mV)
• Redox setpoint (e.g. 720 mV)
• Water temperature (e.g. 24.5°C)
• pH canister fill level (icon with 60%)
• Chlorine canister fill level (icon showing 40%)

Color coding :
Green = everything is optimal. Yellow = slight deviation, currently being corrected. Red = alarm (e.g., canister empty).

Menu navigation : Self-explanatory. Tap on "pH value" → You will see a trend graph of the last 24 hours. Tap on "Settings" → You can change target values.

WiFi module – your pool in your pocket

The integrated WiFi module connects the Automatic Chlor pH to your home network. You then have two access options:

1. Bayrol Pool Access App (iOS + Android):

• Real-time display of all measured values
• Trend graphs (pH/Redox over the last 7 days)
• Push notifications ("Chlorine canister only 20% full")
• Manual control (e.g., dosage boost before a pool party)

2. Bayrol web portal (browser):

• Same functions as the app
• Ideal for PC/Mac
• Export data for your own analyses

Practical example : You're on vacation in Spain. Push notification at 2 p.m.: "pH value 7.6 – Automatic dosing." You open the app and see the trend graph: pH has risen since this morning (probably because the children took a lot of baths yesterday). The system is dosing automatically. Two hours later: pH back at 7.2. Problem solved – without your intervention.

Safety systems – protection against incorrect dosage

Overdosing protection : If the system has dosed more than X liters of chemicals within 24 hours (adjustable limit), it switches off and reports an alarm: "Unusually high chemical consumption – please check system."

Sensor failure detection : If a sensor is defective or delivers unrealistic values ​​(e.g. pH 15.0), the system reports: "pH sensor defective – please calibrate or replace."

Flow switch : Measurement and dosing only occur when the filter pump is running. Prevents chemicals from being dosed into stagnant water (where they would accumulate locally).

Automatic shutdown : If a critical error occurs (e.g., both sensors are defective), the system switches to safety mode and stops dosing.

Why people choose Bayrol Automatic Chlorine pH

"After 5 years of manual dosing, I was fed up with the guesswork. The Automatic Chlor pH was the best investment. The pH is now stable at 7.2 ±0.05 – I could never achieve that manually."
– Mr. K., 54 years old, mechanical engineer, pool 80 m³

"The WiFi module is worth its weight in gold. Last summer on vacation, I saw in the app that the redox value was dropping. The system automatically dosed more chlorine. The pool was perfect when I returned – that would never have worked with tablets."
– Family M., Freiburg, Pool 100 m³

"I've been using liquid chlorine for 10 years because it's the purest form. But manually dosing it was annoying. The automatic system automates my tried-and-tested method – I keep using liquid chlorine, but save 2 hours per week."
– Mr. S., 51 years old, electrician, pool 60 m³

"The level kits are brilliant. I can see on my phone that the pH canister will last for another 3 weeks. No stress, no 'Oops, empty'. I reorder in good time – relaxed."
– Couple from Bavaria, pool 120 m³

✓ You want immediate results (no electrolysis waiting time)
✓ You appreciate the proven professional method

Choose salt electrolysis if:
✓ You want the lowest operating costs
✓ You prefer skin-friendly salt water
✓ You don't want to store canisters

Frequently Asked Questions – Honest Answers

Q: How much liquid chloride and pH reducer do I need per year?
A: Rough estimate for a 100 m³ pool: 100-150 liters of liquid chlorine (approx. €150-220) + 50-80 liters of pH reducer (approx. €80-120) = approx. €230-340/year. Significantly cheaper than multi-tabs (€400-600/year) due to precise dosing without waste.

Q: Is liquid chlorine more dangerous than tablets?
A: Chlorine liquid (13-15% sodium hypochlorite) is corrosive and must be stored safely (childproof, cool, dark). BUT: The automatic dispenser dispenses from sealed canisters – you don't touch the chemicals. With tablets, you inhale chlorine dust when opening them – this is more problematic for your health.

Q: How often do I need to calibrate the sensors?
A: pH sensor: 1-2 times per season. Redox sensor: Rarely (usually only on initial replacement). Calibration takes 5 minutes; buffer solutions are included.

Q: How long do the sensors last?
A: pH sensor: 1-2 years (depending on water quality). Redox sensor: 2-3 years. Replacement sensors cost approximately €60-100.

Q: Do I need high-voltage electricity?
A: No. The automatic unit runs on standard 230V household current. Power consumption: Controller 10W, pumps 8W each = max. 26W. No 400V required.

Q: Can I install the system myself?
A: With some DIY skills: Yes. The Smart&Easy Connector is installed in the piping (after the pump/filter). Mount the controller on the wall. Connect the pumps. Bayrol provides detailed instructions. Alternatively: Installation by a pool technician (approx. €300-500).

Q: What happens during a power outage?
A: The system saves all settings. It restarts automatically after a power outage. If the outage lasts longer than 24 hours, you should add chlorine manually.

Q: Does the system also work in winter?
A: If the pool is heated and in operation: Yes. If the pool is being winterized: Switch off the system, remove the sensors, and store them in a frost-free location.

Q: Can I use pH Plus instead of pH Minus?
A: Yes, the system can also dose pH Plus liquid (if your water is too acidic). Simply change the setting in the menu.

Q: How loud are the pumps?
A: Very quiet. Peristaltic pumps make a quiet humming sound (approx. 40-50 dB) – similar to a computer fan. No annoying clicking.
