Technical Specification Measuring range 0 ... 2.3 mg/l Parameter Ozone Method Colorimetric/ DPD Determination per Checker Disc Sensitivity 0.1 mg/l Number of Tests 100 The Ozone Meter / Testkit HI 38054 is a tool for displaying ozone, which is used for the oxidation of organic substances, that produce colour and odours in drinking water. This ozone meter / test kit for ozone is very suitable for determiningthe presence and amount of ozone. The ozone meter / test kit provides high test accuracy. The ozone meter / test kit for ozone usesthe colorimetric test method, so it works with the concentration determination by color balance. In the kit for ozone, the ozone reacts with the reagent, which then turns pink. The intensity of the pink color is directed proportional to the amount of ozone. In the checker disc you need to rotate only at the turntable, until they see the color of the reagent. In the lower window of the checker disc, you can then read off the exact value of the ozone concentration.
