Simple Gas Detection System TH-1000B
The Simple Gas Detection System TH-1000B provides real-time monitoring of hazardous gas levels, ensuring a safe environment for workers. Equipped with advanced sensors, it allows for quick response to potential gas leaks, helping to prevent accidents and maintain compliance with safety regulations.
Overview
The on-line monitoring and pretreatment system is applied to 24-hour continuous on-line monitoring of on-site gas concentration. It is equipped with 7-inch high-definition color screen to display on-site concentration, over standard on-site audible and visual alarm (optional), remote signal GPRS, DTU, Lora and other transmission. The gas sensor of international famous brand is adopted. The main detection principles include: gas sensor based on the principles of electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photo ion, etc..
