BH-4AS Zetron Combustible Gas Leak Detector In Underground Channels
BH-4AS Portable Multi-gas Detector
BH-4AS portable multi-gas detector could detect combustible gas, O2, and other two types of toxic gases continuously and simultaneously. It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers' life and avoid damage to the relevant equipment.
Detecting gas:
CH4, H2S, CO, O2
