BH-4A Portable Multi Gas Detector

SKU: BH-4A
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

Description

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.

*Large LCD, more intuitionistic, abundant and clear indication.

*Compact design, easy carrying.

*High strength engineering plastics and compound anti-slippery rubber; high strength, water-proof, dust-proof and explosion-proof.
