Low Power RS485 Electrochemical H2S Gas Sensor

Key Applications & Use Cases

Industrial Chemical Area H2S Monitoring: Suitable for chemical storage tanks, pipeline joints and workshop operation zones. Adopts electrochemical sensing principle with a measurement range of 0~50ppm, capturing H2S concentration fluctuations in real time. Features a compact design (0.6kg) and wide voltage supply (5~28VDC), with RS485 ModBusRTU protocol enabling multi-point networking. It withstands -20~60℃ operating temperature and 0~99.9% RH humidity, effectively alerting to leakage risks and protecting personnel safety.
Sewage Treatment Plant H2S Detection: Ideal for aeration tanks, sludge dewatering areas and anaerobic digestion units. While measuring 0~50ppm H2S, it simultaneously monitors temperature (-40~+80℃) and humidity (0~99.9% RH). The electrochemical sensor with a lifespan of <2 years ensures stable performance, and the RS485 signal output integrates with central control systems to trigger ventilation and reduce toxic gas accumulation.
Underground Pipeline & Confined Space Monitoring: Applied to sewer networks, pump stations and underground vaults. The proprietary compensation algorithm guarantees measurement accuracy even in low-temperature environments, and the ModBusRTU protocol enables remote data transmission. Its 5~28VDC wide voltage supply and compact structure allow easy installation, providing reliable H2S, temperature and humidity monitoring for confined space entry safety.
Waste Disposal Site H2S Early Warning: Fits landfill sites, waste sorting workshops and composting areas. Real-time monitoring of 0~50ppm H2S concentrations, paired with temperature and humidity detection, supports early warning of toxic gas buildup. The device’s anti-interference performance and stable RS485 data output ensure seamless connection to site alarm systems, while its -20~60℃ operating range adapts to outdoor fluctuating temperatures.
