BH-4A with EX, H2S, CO, O2

The BH-4A is a compact and rugged portable multi-gas detector designed for real-time monitoring of four key hazardous gases: combustible gases (EX), hydrogen sulfide (H₂S), carbon monoxide (CO), and oxygen (O₂). Engineered for industrial safety, this device offers accurate gas concentration readings with high sensitivity and fast response times, ensuring protection in confined spaces and hazardous environments.

Equipped with a large LCD screen, visual/audible/vibration alarms, and a long-lasting rechargeable battery, the BH-4A is widely used in oil & gas, mining, chemical processing, wastewater management, fire safety, and confined space entry operations.
