1. Product Overview
This industrial/commercial point - type combustible gas detector, built for industrial scenarios, is an explosion - proof safety monitor. It integrates concentration display, audible - visual alarm, and ambient temperature monitoring.Using a catalytic combustion sensor and natural diffusion, it detects gas levels with high sensitivity and repeatability, quickly catching small leaks. An industrial LCD screen shows real - time concentration and temperature. When thresholds are hit, it triggers alarms, sends control signals for exhaust systems, enabling automated “monitor - alarm - respond” to secure on - site safety.
Supporting RS485, it connects seamlessly to the CL - M201 controller for real - time data/status upload, allowing centralized management of multiple detectors. Paired with M201, PowerBus two - wire tech simplifies wiring, cuts costs, and boosts stability—ideal for large industrial setups.Based on embedded micro - control, it’s easy to use, feature - rich, and reliable. Its explosion - proof design handles harsh conditions (high temp, humidity, dust). Plug - and - play installation lowers maintenance barriers, delivering solid gas monitoring for industrial/commercial sites.
