4 in 1 Multi gas Detector BH-4AS O2、CO、H2S、EX USB rechargeable Explosion-Proof
BH-4AS 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.
INTRODUCTION
