H2S SensorH2S Sensor SHANGHAI SHENKAI Based on micro-processing technology, the sensor utilizes advanced metal oxide semi-conductor sensor (MNOS adsorption technique), linearly transforms detected H2S gas concentration into 4-20mA and redundant RS485 interface signal as output (Modbus RUT communication protocol). In addition, the sensor provides gas concentration and status display, and early-warning, alarm and failure contact output. Easy to calibrate. ● Working Voltage : 24VDC |
