CL-W6602 Residual Chlorine with Polarography

CL-W6602   Residual Chlorine with Polarography

Applications：

Industrial on-line residual chlorine meter is a water

quality on-line monitoring and control instrument with

microprocessor. It is widely used in drinking water

treatment plant, drinking water distribution network,

water quality treatment engineering,swimming pool,

sewage treatment, water quality disinfection and other

industrial processes, to continuously monitor and

control the residual chlorine value, pH value &

temperature value in water.

Feature：

●LCD display.

●Intelligent menu operation.

●data record & curve display.

●Multiple automatic calibration functions.

●Three relay control switches.

●High alarm & low alarm, hysteresis control

●4-20mA&RS485 multiple output modes.

●Residual chlorine, temperature and current, etc.simultaneously showed in one screen.

●Password protection function to prevent misoperationby non-staff.
