The most widely used sanitizer can be measured real time with use of our FCL series free chlorine sensors. The 4-20 mA fixed output permits interfacing to a wide variety of instrumentation options. The FCL-02 has a working range of 0-2ppm free chlorine while the FCL-10 is used for 0-10ppm measurements. The newest addition to the line is the FCL-05 for 0-5ppm measurements. Sensor output is automatically temperature compensated.

      This most effective sanitizer can be measured real time with use of our CLD series chlorine dioxide sensors. The 4-20 mA fixed output permits interfacing to a wide variety of instrumentation options. The CLD-02 has a working range of 0-2ppm chlorine dioxide while the CLD-10 is used for 0-10ppm measurements. CLD-01 is the newest addition to the line for 0-1ppm measurements. Automatic temperature compensation is provided standard.
