Product Description

4 in 1 Multi Gas Detector BH-4A O2 H2S CO LEL Air Quality Detector Gas Analyzer

 

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.

 

INTRODUCTION

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.

*Full functions, easy operation.
