CD4: Chlorine Dioxide Sensors

Special Features :

4-20mA Direct Output
500V Input to Output Isolation
Multiple ranges to select from
Replacement for other 4-20mA ClO2

Applications :

The CD4 series (chlorine dioxide sensors) feature amperometric measurement technology.Designed for disinfection applications in water treatment, for use with chlorine dioxide, chlorine generators, pools, etc., these sensors are available in several ranges for detecting ppm level of chlorine dioxide or free chlorine to better help our customers. Choose the CD402 for 0-2ppm and CD410 for 0-10ppm of chlorine dioxide.
Sensors output a 4-20mA signal. Membrane cap and fill solution are easily replaceable to maximize sensor life
Sensors can be used in new installations with Omicron's flow cell or installed as replacement for other
4-20mA output ClO2 (Consult Omicron for compatibility).
An optional flow meter is available to help provide consistent flow for added system stability
