Free Chlorine Sensors

The FCL series (Free Chlorine Sensors) feature amperometric measurement technology. Designed for disinfection applications in water treatment, for pools, etc., these sensors are available in three ranges for detecting ppm level of free chlorine. Choose the FCL502 for 0-2ppm, FCL505 for 0-5ppm and FCL510 for 0-10ppm of free chlorine.

Typical applications include:

Industrial wastewater
Cooling water
Bottle rinsing
Irrigation water in agriculture

Sensors output a 4-20mA signal scaled to 0-2, 0-5 or 0-10ppm. Membrane cap and fill solution are easily replaceable to maximize sensor life.

Sensors can be used in new installations with Opticlear flow cells or installed as a replacement for other 4-20mA output free chlorine sensors.

An optional flow meter (FM001) is available to help provide consistent flow for added system stability.
