Free Chlorine Sensors

The new FCL400 series free chlorine sensors from Sensorex feature amperometric measurement technology. Designed for use in water treatment disinfection applications and for use with chlorine generators, pools, and drinking water, these sensors are available in several ranges for detecting ppm levels of free chlorine. Choose the FCL402 for 0-2ppm, FCL405 for 0-5ppm and FCL410 for 0-10ppm of free chlorine.

Sensors output an isolated 4-20mA output signal Membrane cap and fill solution are easily replaced to maximise sensor life.

Sensors can be used in new installations with Sensorex flow cell or installed as replacement for other 4-20mA output free chlorine (FCl) sensors (Consult Sensorex for compatibility).

An optional flow meter is available to help provide consistent flow for added system stability.
