Cole-Parmer 二氧化氯传感器，0到百万分之2，4至20 mA输出

Cole-Parmer® Chlorine Dioxide Sensor, 0 to 2 ppm, 4 to 20 mA output

An economical replacement for other chlorine and chlorine dioxide sensors
4 to 20 mA output signal feeds directly into most PLCs, dataloggers, or chart recorders
Multiple ranges available
Designed for use in water treatment applications. Sensors measure on-line, in real-time, and are available in two ranges for detecting ppm levels of chlorine dioxide within a pH range of 4 to 11. Sensors have some cross sensitivity with ozone. Three levels of free chlorine can be measured between pH 5.5 to 8.0. Sensors have some cross reactivity with ozone, bromine, and chlorine dioxide.

Sensors feature an internal ATC and signal conditioner to provide a 4 to 20 mA output signal over the measurement range. Sensors and flow cells can be used for new installations or as replacements for other 4 to 20 mA output sensors. Install in existing loop-powered systems or order powered panel meter 94785-12. 

Service life exceeds one year in most applications. Membrane caps and fill solution can be replaced to maximize sensor life; order separately.
