Description
Hydrogen Sulphide ppm detector – Ex proof, fixed type
ATEX, FM, UL certified Sensor transmitter for online, continuous measurement and alarm of toxic level (ppm range) of hydrogen sulphide gas in ambient air or ducts, flameproof / explosion proof certified Zone 1, 2, with / without display, contact relays, flashing alarm LEDs, RS485 serial interface with Modbus RTU protocol
Model: XGST-028
We offer industrial grade explosion proof ATEX, FM, UL approved hydrogen sulphide detector for toxic range ppm measurement. It is suitable for installed hazardous zone 1, 2 classified area as per OSHA, WHO work-safety requirement. Eg. chemical plant, tyre manufacturing unit, polymer industry, manufacturing plants, warehouse etc.
The detector comes with universal mounting, hence can be installed at walls, surfaces or in ducts.
It offer linear, proportional analog output in industry standard current signals, and suitable for integration with BMS, SCADA system. It has unique feature of auto diagnostic watch dog with zero point tracking feature. Due to its 10-bit microprocessor based control unit, it offer high accuracy over long term. The detector is also equipped with sintered filter with flashback arrestor for enhanced safety.
About Hydrogen sulphide H2S
Hydrogen sulfide is the chemical compound with the formula H ₂S. It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs. It is very poisonous, corrosive, and flammable gas. Hence, it need to be monitored continuously at area of storage, usage, application etc.
