Industrial online residual chlorine meter

APURE Online water analyser pH and chlorine tester/controller meter &sensor with 4-20mA

TC-2200 is an online intelligent residual chlorine controller produced by our company with imported technology. It uses imported components and permeable filmhead, based on the latest polarographic analysis technology, advanced production technology and surface paste technology. The application of this series of adcanced analytical techniques to ensure the stability, reliability and accuracy of the long-term work of the instrument. 

Characteristics:

●Large screen lattic liquid crystal display.

●Multi-parameter simultaneous display: residual chlorine value, hypochlorite value, pH value, temperature, output current.
●With the recovery factory setting function, the slope correction function.
●Manual/ automatic pH compensation and temperature compensation.
●Communication function(optional): it has RS485 communication interface(Modbus protocal is partly compatible), and the residual chlorine value corresponding to the current output of 4-20mA can be set arbitrarily.
●Optoelectronic isolation 4-20mA current output.
●Hysteresis arbitrary setting function to avoid switching relay frequent action function.
●Watchdog function: make sure the meter doesn't crash.
●Core devices are from foreign famous brands.
●Power failure protection>10 years.
