Product Details

Portable air analyzer, multi gas detector/gas analyzer

BH-4S portable multi-gas detector could detect combustible gas, O2 and other two types 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 on the relevant equipmentsuipments.
