ICO TDS Sensor + Calibration and Regeneration Kit

Keep your ICO sensors accurate and long-lasting

Regenerating your sensors restores their performance, while regular calibration of the pH (blue), ORP (orange: chlorine/bromine), and salt (yellow) probes ensures precise and reliable readings. Together, regeneration and calibration extend the lifespan of your sensors.

The ICO Regeneration & Calibration Kit is designed to maintain both reliability and durability. It’s fully compatible with ICO Pool and ICO Spa devices.

When to calibrate
After your first season, we recommend calibration:

• Each time you restart your pool or spa (or every 6 months if not winterized),

• Or whenever you notice measurements drift.

Your ICO comes pre-calibrated at the factory, so there’s no need to calibrate it the very first time you use it.
