Water ORP Transmitter Detection Sensor

ORP transmitter adopt double high-impedance three-electrode system, with online one-key calibration, real-time temperature compensation, electrode loose alarm, electrode good or bad alarm during calibration, and power-off protection (the calibration result and preset data will not be lost due to shut down or power failure) , Over-current protection, over voltage protection, high measurement accuracy, fast response, long life and so on.

This product is suitable for: electroplating, yeast, food processing, sewage treatment, metallurgy, environmental protection and other occasions.

The linear relation between analog signals and the corresponding physical value:

0 to 5 v output:

(-1000~1000mV range)：ORP=ORP output voltage*400-1000；

(-2000~2000mV range)：ORP=ORP output voltage*800-2000；

0 to 10 v output:

(-1000~1000mV range)：ORP=ORP output voltage*200-1000；

(-2000~2000mV range)：ORP=ORP output voltage*400-2000；4-20 ma output:

(-1000~1000mV range)：ORP=(ORP current-4)*125-1000；

(-2000~2000mV range)：ORP=(ORP current-4)*250-1000；

Due to the ORP electrode in the measurement environment vulnerable to pollution cause electrode signal affected, in order to ensure the ORP sensor can normally use for a long time, usually need to make a correction on a regular basis through the calibration of transducer (once a month). Depending on the water samples of specific calibration cycle.
