H2S Gas Transmitter, 12 to 24 VDC Working Voltage, 0-100 ppm, RS485 Output

Product Datasheet

The L-com SRAQ-D461-2 hydrogen sulfide (H2S) constant potential electrolytic gas transmitter is most suitable for IoT applications. This transmitter is used to detect the presence and concentration of hydrogen sulfide gas and has a Modbus-RTU output. Our hydrogen sulfide industrial transmitter is specifically developed for public restrooms, manufacturing facilities, warehouses, and other commercial buildings where hydrogen sulfide gas concentration is a concern.

This wall-mounted device features low power consumption, good repeatability, and stability. The hydrogen sulfide (H2S) gas transmitter requires a 12 to 24 VDC power supply and has a detection range of 0 to 100 ppm. The SRAQ-D461-2 transmitter produces a series of oxidation-reduction reactions within the sensor that produce a current. The amount of current is directly proportional to the concentration of hydrogen sulfide.
