Ondilo ICO Calibration Kit box
Ondilo ICO Calibration Kit box is a calibration kit that allows you to ensure that the measurements of your ICO are more precise and thus improve its performance.
In other words, you tell the device what the ideal values are via the calibration. The more the device is optimized, the healthier your water is.
By default, your ICO is in the factory calibrated. That's why we recommend the sensors recalibrate each time you restart your pool or spa. Or every 6 months if you do not winterize or if you notice a deviation in the measurements.
