Portable Diffusion Type 4-Gas Multi Gas Detector (CO, O2, H2S, CH4/LEL) for Mining Use
**Applications:**
The CD4 portable multi-gas detector is an intrinsically safe and explosion-proof device designed to detect various hazardous gases. It can simultaneously monitor up to four atmospheric hazards: carbon monoxide (CO), oxygen (O2), combustible gas (LEL), and hydrogen sulfide (H2S). Compact and lightweight, the CD4 features audible, visual, and vibrating alarms that activate in case of low or high gas concentration levels.
This versatile gas detector has transformed the market with its wide range of features, including water resistance and robust performance. Primarily used in underground coal mines and mine safety inspections, it is also widely applied in firefighting, confined spaces, chemical industries, oil sectors, and other environments where hazardous and toxic gases need to be monitored.
