SUPMEA BH-4A

Portable multi-gas detector for gas, O2 and other two types toxic gases

Description

SUPMEA BH-4A Portable multi-gas detector for gas, O2 and other two types toxic gases

Ensuring safety in industrial environments often requires monitoring multiple hazardous gases at the same time. The SUPMEA BH‑4A portable multi‑gas detector is designed to detect combustible gases, oxygen (O₂), and two types of toxic gases (e.g. CO, H₂S) simultaneously and continuously.
