PACON 2500 Online Chlorine Analyzer（DPD）

The PACON 2500 analyzer continuously detects the online residual chlorine concentration in water and uses the authoritative and reliable DPD colorimetric method. By automatically adding buffer reagent, the sample is adjusted to a certain pH range and the DPD becomes purple with the concentration of residual chlorine. The color depth depends on the chlorine content of the water sample.

Measurement parameters:

● Chlorine

Application:

● Tap water

● Drinking water pipe network

● Disinfection process

● Reverse osmosis

● Cooling water
