BH-4A Portable Multi Gas Detector

BH-4A Portable Multi Gas Detector

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.

We provide gas detector OEM/ODM service

Detecting gas:

Combustible gas, H2S, CO, O2



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

*32-bit built-in MCU, high reliability and self-adaptation ability.
