Bosean ATEX certified Bosean Portable multi gas detector for CO, O2, H2S, LEL, CH4

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 equipments.
