**Name: Portable Multi-Gas Detector**
**Applications:**
The CD4 portable multi-gas detector is an intrinsically safe and explosion-proof instrument designed to detect hazardous gases. It can simultaneously monitor up to four atmospheric hazards, including carbon monoxide (CO), oxygen (Oâ‚‚), combustible gas (LEL), and hydrogen sulfide (Hâ‚‚S). Compact and lightweight, the CD4 activates audible, visual, and vibrating alarms in case of low or high gas concentration levels.
This device stands out for its versatility, reliability, and overall value. The water-resistant line of portable gas detectors has revolutionized the market with a wide range of advanced features. It is primarily used in underground coal mines and mine safety inspections. However, it is also widely applied in firefighting, confined spaces, chemical industries, oil sectors, and any environment where hazardous and toxic gases need to be monitored.
