Why are the ICO measurements different from the strips?

Your ICO is programmed to measure pH, ORP (disinfection) and TDS (water conductivity). It is possible to observe differences in results between analyses carried out by ICO and those carried out with other instruments, such as test strips.

• the chemical values sought by the two instruments are different.

• the way the measurement is taken (depth, location or time of analysis) has also a strong impact on the result.

It is therefore not relevant to compare two tools that are not identical. The reliability of ICO measurements allows you to keep your water balanced for a long time and to preserve the equipment of your pool or spa.

What does ICO measure compared to strips?

pH measure

You can check the accuracy of your ICO's pH measurement by doing a comparative test with mineral water at home.

Disinfection rate (ORP /REDOX)

There are three different types of chlorine: ICO measures active chlorine. Most strips measure total or free chlorine which is not an indicator of water disinfection.

The conductivity (TDS)

ICO measures TDS, or Total Dissolved Solids in water.

The strips measure TAC and TH and give partial measurements.
