Product Details
Bosean BH-4S ATEX blue portable co h2s o2 EX multi gas detector
Description of Multi 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
equipments.
