Description
Ondilo ICO conductivity sensor (TDS) – for ICO Pool and ICO Spa
The Ondilo ICO conductivity sensor, also known as the TDS sensor (Total Dissolved Solids), measures the amount of dissolved substances in your pool or spa water. This gives a clear picture of the salt content and overall water quality. The sensor is particularly essential for pools and spas that use a salt chlorinator.
With continuous measurements, the conductivity sensor helps monitor the water balance and gives timely alerts when the salt content is too high or too low. This way, you maintain optimal conditions for disinfection and comfort.
Durable and low maintenance
The conductivity sensor has a long lifespan of 5 to 6 years and requires little maintenance. Unlike the pH and Redox sensors, calibration is generally not required for this type of sensor. Occasional simple cleaning is enough to maintain measurement accuracy.
The sensor is fitted using the trusted Twist & Lock system, so replacement can be carried out quickly and without tools.
Real-time data via the Ondilo app
After installation, the sensor automatically sends data on the salt and mineral content to the Ondilo app. This gives you real-time insight into the conductivity of your pool or spa water. If the salt content is out of balance, you receive a notification with recommendations for correction. This makes maintenance easier and more accurate than ever.
