The CL-3000C is an on-line analyzer built to measure Free Chlorine Levels in the range of 0.01–20 ppm in drinking water, waste water and process applications.
The measuring systems is potentiostatic based and provide an accurate and stable reading with an auto. temperature compensation.
The reading can be sent through the isolated 4-20 mA Output to any control device, computer or data logging system and 3 SPDT relays can provide a local Alarm/control dry contact signal or proportional control signals (PFM or PWM).

The Analyzer is provided with an IP-65 enclosure with a clear door and 2 lockers. The  ontroller has the option for Key board lock.
