BH-4A Portable Multi Gas Detector

Description

BH-4A 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 equipments.

Features:

*Natural diffusion sampling method and high-sensitivity sensor, with high sensitivity and repeatability.
