Free chlorine sensors

With three models covering the 0-2ppm, 0-5ppm and 0-10ppm 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.
