Do you keep your pool or hot tub crystal clear with the ONDILO ICO smart pool monitor or the ONDILO ICO Spa digital water tester? In that case, you will certainly appreciate the replacement blue pH sensor, thanks to which your monitor will serve as a new one for many years to come.

The blue replacement sensor measures the pH level - indicating whether the water is acidic or alkaline. The right pH ratio has a good effect not only on the skin, but also on the life of the pool and whirlpool. If you replace the sensor every 5 years, you can be sure that your monitor will give you reliable pH measurements.

The sensors report the measured values via a smart monitor to your phone, where you can monitor them in a simple mobile application for iOS and Android. Thanks to continuous analysis, you prevent excessive use of chemicals or the necessary water change. The package also includes a calibration kit, which must be used before each new season to optimize the monitor.

• Measure the PH of your pool and whirpool
• Keep water crystal clean
• Calibrate your ONDILO ICO monitor

What values does the blue sensor measure?

The abbreviation pH shows us the ratio and concentration of protons and hydrogen ions, i.e. whether the water is acidic or alkaline. The right pH value is very important not only for our skin, but also for the life of the pool and whirlpool components. The PH sensor shows you values and balance through a mobile application, helping to maintain a constant ideal pH level.


What can the ONDILO ICO smart monitor do?

The ONDILO ICO smart pool monitor and the ONDILO ICO Spa digital water tester are indispensable helpers in maintaining your wellness. Whether you care for a swimming pool or hot tub, the smart monitor constantly monitors the temperature and ideal pH through sensors, maintaining the right level of disinfection, water conductivity and concentration of salt and other minerals. You control the monitor with a free mobile application that you download from the Apple Store or Google Play. By connecting to a Wi-Fi or Bluetooth, you can very easily install the application on your smartphone, and you will have full control over the condition of the pool and whirlpool.

Why, when and how to change sensors

In order for your ONDILO ICO smart pool or whirlpool monitor to always work 100%, you need to calibrate it before every season and replace all sensors every five years. Thanks to the Twist & Lock system, the sensors change very easily and quickly. Once a season, you then perform a calibration that analyses, cleans, and optimizes the features of all sensors.

How to use the calibration kit?

A calibration kit is included with the replacement sensor, which optimizes the performance of all sensors, as well as your ONDILO ICO smart pool monitor. The kit contains three special buffer solutions, a stand and user manual, thanks to which you can easily optimize your monitor yourself at home. You monitor the calibration process and results via the free mobile ICO application for your smartphone, which guides you step by step through the process. The solutions are medically harmless and after calibration you can pour them into the drain.
