The online residual chlorine analyzer is highly intelligent and flexible, capable of simultaneously measuring residual chlorine, hypochlorous acid, pH, and temperature.
It is widely used in industries such as electric power, water supply, pharmaceuticals, chemical engineering, and food for continuous measurement of residual chlorine and pH value in water.
Large dot-matrix LCD.
Simultaneous display of multiple parameters: Residual chlorine value, hypochlorous acid value, pH value, temperature, output current, etc., intuitive and easy to read, with range over-limit prompt.
Functions of restoring factory settings and slope correction.
Manual/automatic pH compensation function and temperature compensation function.
Communication Function (Optional): Equipped with an RS-485 communication interface (partially compatible with MODBUS protocol); the residual chlorine value corresponding to 4~20mA current output can be set arbitrarily.
Photoelectrically isolated 4-20mA current output.
An arbitrary hysteresis setting function to avoid frequent action of switching relays, with functions of setting the switch on/off.
Watchdog function: Ensures the instrument will not crash.
Core components are from well-known brands.
Electrode cable length: 5m as standard if not specified.
Electrode installation method.
Power supply: AC220V as standard if not specified.
Customization available for special requirements.
