Sensorex' FCL500 series free chlorine sensors use advanced amperometric measurement technology to provide highly accurate monitoring of free chlorine in process applications. With three models covering the 0-2 ppm, 0-5 ppm and 0-10 ppm ranges, FCL500 sensors can be used in new installations or as a field replacement for existing sensors in drinking water disinfection and distribution applications, food and beverage production, cooling water, and other industrial water treatment systems.

The new device has an upgraded temperature correction curve for improved performance. Its new membrane design features a mesh reinforcement clamp for increased stability and added durability. The 4-20mA isolated signal output is enhanced to eliminate ground loop errors, reduce noise, and block high voltage transient surges.

For real-time free chlorine monitoring, the FCL500 series sensors interface with PLC, SCADA and other process control systems via the 4-20mA output. A large electrolyte reservoir with an easily replaced membrane cap and solution reduce maintenance intervals and maximize sensor life.

Sensorex is a global leader in design and manufacture of quality sensors for water applications. The company offers more than 2000 sensor packages for pH, ORP, dissolved oxygen free chlorine, chlorine dioxide and other specialty measurements, as well as a full line of sensor accessories. Its expert technical support engineers solve analytical sensor challenges with custom designs and off the shelf products.
