Long lifetime RS485 Electrochemical SO2 Gas Sensor

Key Applications & Use Cases

Power Plant Flue Gas SO2 Detection: Our Power plant flue gas SO2 detector, built with an Electrochemical Gas Sensor, is ideal for coal-fired power plant emission monitoring and desulfurization system efficiency evaluation. This RS485 gas sensor delivers real-time SO₂ concentration readings across a 0-20.00ppm range, while simultaneously tracking temperature (-40℃~80℃) and humidity (0~100% RH). The sensor’s lifespan of >2 years ensures long-term stability, and its RS485 ModBus RTU output integrates seamlessly with environmental monitoring platforms for compliance reporting.
Industrial SO2 Monitoring: As a dedicated Industrial SO2 monitoring sensor, this device uses an Infrared absorption SO2 gas sensor to deliver precise measurements for smelting workshops, chemical production exhausts, and boiler flue gas discharge. The compact design and 10-30VDC wide voltage supply support multi-point networking, and it operates reliably in -20~50℃ temperatures and 15~90% RH humidity (anti-condensation), providing early alerts for excessive emissions to safeguard ecological safety.
Environmental Emergency SO2 Early Warning: This SO2 Gas Sensor is engineered for rapid deployment in chemical park perimeter monitoring and atmospheric quality emergency response. Its proprietary compensation algorithm maintains accuracy even in high-humidity environments, and the ModBus RTU protocol enables remote data transmission. With robust anti-interference performance and a stable RS485 data output, it connects seamlessly to emergency alarm systems, making it a critical tool for toxic gas leakage early warning.
