GT-AT0617 Series Underground Shaft Combustible Gas Monitoring Device integrates advanced monitoring technologies for complex underground scenarios. It adopts a diffusion-type laser sensor to detect methane (0~100)%LEL with ±2%F.S accuracy, supporting gas leak detection, infrared remote control, and low power consumption (three-year typical battery life). The DC3.6V device has adjustable sampling (20s~1800s) and heartbeat intervals (1h~24h), 4G communication, and GPS/Beidou positioning. Unique features include groundwater level immersion monitoring, vibration early warning, and AI image monitoring with real-time transmission. With explosion-proof protection, IP68 rating, engineering plastic enclosure, it works stably at -40°C~70°C. Designed for vertical pole installation, it supports customized extensions and ensures comprehensive, intelligent monitoring of underground shafts with high reliability.
