POP-8300 Free Chlorine online controller
- On-line analysis of municipal water tank disinfection
- Chlorine supplement control of pipe secondary pressurization (no negative pressure)




ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.


Measure range :TUR-6101 (0~5NTU) ;TUR-6102 (0~100NTU)


Free Chlorine (DPD) online automatic analyzer is mainly used for real-time monitoring of water plants, secondary water supply of pipe network, medical wastewater, kidney dialysis medical water, food and beverage water, swimming pools, circulating cooling water, enterprise discharge wastewater and other occasions.


Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.


Widely used for online measurement of acid&alkali in low concentrations and the low viscosity single-phase fluid of non-trade settlement process.
