The FCLTX Series of free chlorine sensors feature amperometric
measurement technology. They are designed for use in water
treatment disinfection applications and for use with chlorine
generators, pools, etc. The sensors are available in several ranges
for detecting ppm levels of free chlorine. Choose the FCLTX-102
for 0 to 2 ppm, FCLTX-105 for 0 to 5 ppm and FCLTX-110 for
0 to 10 ppm of free chlorine. Membrane caps and fill solution are
easily replaced to maximize sensor life. Sensors can be used in
new installations with Omega flow cell or installed as replacement
for other 4 to 20 mA output free chlorine (FCl) sensors.
