EM-CH4 甲烷氣體報(bào)警儀
EM-CH4 Methane Gas Alarm Instrument Overview
The EM-CH4 methane gas alarm instrument is a professional safety monitoring device designed to detect methane (CH4) concentrations in various environments. Utilizing advanced electrochemical sensing technology, this portable instrument offers precise measurements with a resolution of 1ppm and ≤±5% accuracy. It features diffusion sampling (optionally upgradeable to pump suction) with rapid response time under 40 seconds. The compact design (115×55×28mm, 140g) incorporates a bright LCD digital display with backlight, while touch-sensitive buttons ensure easy operation in low-light conditions. Triple-alarm functions including sound (≥80dB), flashing LED lights, and vibration provide comprehensive warning when methane levels exceed user-defined thresholds. The device operates on 3.6V-4.5V DC dry batteries with environmental adaptability from -15℃ to +45℃ and ≤95%RH humidity. Its robust construction and 2-year sensor lifespan make it suitable for industrial safety, residential gas leak detection, and energy sector applications.14
