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 |

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