The sensor detects virtually all flammable gases and vapors — including methane, propane, butane, and solvent vapors — measuring concentrations from 0–100% LEL (Lower Explosive Limit) with a linear, stable response. Trusted for decades in industrial safety, confined space entry, and hazardous atmosphere testing, catalytic bead technology delivers reliable performance across wide temperature and humidity ranges where other sensor types struggle. Its broad-spectrum sensitivity makes it ideal for environments where the specific combustible gas may be unknown, providing dependable protection against fire and explosion hazards. Simple to calibrate and maintain, the sensor offers fast response times and long service life, making it the practical choice for oil and gas, utilities, wastewater, HVAC, and general industrial applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstructions\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReplace the sensor module.
