CL6587 Chlorine Controller

CL6587 Chlorine Controller

CL6587 Chlorine Controller

The CL6587 Chlorine controller is a surface mounted controller designed for direct reading of free chlorine in ppm or mg/L and can operate in automatic, measure or simulated modes.

The CL6587 is Designed to work with either an open amperometric chlorine cell or our SZ283 Potentiostatic Chlorine Sensor, when combined with the SZ283, the CL6587 is designed to measure Free Chlorine / Residual Chlorine, Chlorine Dioxide or Bromine.

Key Features

The CL6587 offer some key features including two industry standard 4-20mA outputs, which allow for PID control or transmission of the measured values. During PID control through the analog output, the level of the actuation is displayed. The user can select an FM regulation (pulse frequency) or WM (pulse width) addressed to the assigned relay.

The CL6587 has a IP65 protection rating and offers easy installation, it is suitable for wall mounting, or for DIN rail and handrail by means of optional accessories. It also has a large black and white graphic display that shows the measurement values and guides the user through set-up, configuration and normal operation using the dedicated keys to directly access zero and sensitivity calibration as well as initial configuration.

The CL6587 also has a dedicated relay for alarm to an external device to initiate self-cleaning. This function is fully programmable through the controllers’ software and uses a universal power supply from 85 to 264 Vac, 50/60 Hz, with low voltage option that allows to power the unit from 9 to 36 Vdc or from 12 to 24 Vac, 50/60 Hz.


Applications for the CL6587 chlorine controller include aquaculture, pharmaceutical, chemical industry, textile industry, drinking water, water treatment, swimming pools, food and beverage and many more with substances such as free chlorine, combined chlorine, total chlorine, chlorine dioxide, dissolved ozone, hydrogen peroxide and peracetic acid.

CL6587 Range

Chlorine Range
0 ÷ 200.0 ppb / μg/l
0 ÷ 2.000 ppm / mg/l
0 ÷ 20.00 ppm / mg/l
0 ÷ 200.0 ppm / mg/l
0 ÷ 2000 ppm / mg/l
-10.0 ÷ 110.0 °C, 14.0 ÷ 230.0 °F

As a sophisticated Chlorine Controller, the CL6587 can take an input from a temperature sensor to provide automatic temperature compensation across a user-configurable range.
