ONDILO ICO – ORP Chlorine-bromine Sensor (Orange) + Calibration Kit

What is the purpose of the platinum ORP sensor?

ORP stands for oxidative reduction potential. Thanks to which, we can check whether the water does not contain too much chlorine, bromine or air and thus determine its health safety with certainty. ORP shows us whether the water has an ideal bacteriological quality and we will not be sick if, for example, we accidentally swallow the water while diving. This information is very important, especially if children are swimming in the pool.

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.

It's said - there is truth in wine and health in water. Thanks to its origin and specialization, the French brand Ondilo has taken this saying more than serious. Judge French wines for yourself, rather entrust the health safety of the water in your pool or whirlpool to the care of Ondil's smart water sensors.
