AT0605 Series Underground Shaft Combustible Gas Monitoring Device is a professional methane monitoring tool designed for underground shaft scenarios. Adopting a diffusion-type measuring method and high-precision laser sensor, it covers a measurement range of (0~100)%LEL with an accuracy of ±2%F.S, ensuring accurate detection of methane leaks. Powered by a DC3.6V battery, it boasts low power consumption and a typical service life of three years, requiring no frequent battery replacement. The device supports 4G communication and GPS/Beidou positioning, enabling real-time data transmission and precise location tracking. With explosion-proof grade Ex db IIC T6 Gb and IP68 protection, it works stably in harsh environments (-30°C~70°C, ≤100% RH no condensing). It features infrared remote control, no installation required for immediate use, and adjustable sampling (20s~1800s) and heartbeat intervals (2h~24h), making it ideal for safe and efficient methane monitoring in underground shafts.
