Chlorine XP is an analyzer that uses the DPD colorimetric method for online measurement of free or total chlorine in water. Reagent is added to the sample, and chlorine concentration is calculated by measuring the intensity of the resulting color with a colorimeter.
It is used for disinfection control in drinking water distribution, treatment plants, pools, process water and the food industry. If desired, pH and temperature can also be measured on the same instrument; pH is important for correctly interpreting the DPD reaction.

- Flow cell, colorimeter, display and 4–20 mA output module options
- Planned maintenance with an annual replacement kit
