● Drinking water: tap water chlorination process and factory outlet, pipe, tap
● Sewage: Disinfection process of municipal wastewater, industrial wastewater and hospital wastewater treatment
● Industry: industrial circulating cooling water and cooling water more than chlorine (total) chlorine measurement
Thechlorine in chlorine (ClO-, HClO, Cl2) and chlorine(chloramines, chlorine and ammonia compounds that, in water are NH2Cl, NHCl2and NHCl3, and other derivatives of chlorine) there are two kinds of forms.Adjust the pH value of water sample to the proper range of residual chlorine,which can make the DPD become purple, analysis of the content of this colorchange can be obtained by chlorine. By adjusting the reagent, DPD2000 can alsobe used to measure the total chlorine concentration.
● Continuous or intermittent measurement - Automatic Chroma and turbidity compensation
● Sampling, mixing, color sealing process, automatic operation, short measurement cycle
● Unique mixing system, can make the sample fully mixed, high measurement accuracy
● Precision peristaltic pump control technology, so that the reagent consumption greatly reduced
● Simple operation, low maintenance, daily use can be unattended
● Self-diagnostic function, such as the lack of reagent alarm, the detection of the media sample off alarm
