Industrial online residual chlorine meter
APURE Online water analyser pH and chlorine tester/controller meter &sensor with 4-20mA
Residual Chlorine: 0-20.00mg/L
0~99℃(resolution ratio 0.1℃)
1 set of 4-20mA signal
AC 220V±10% 50/60 HZ
●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.
