Multifunction 4 in 1 Gas Detector Oxygen Methane Meter Hydrogen Sulfide Carbon Monoxide Gas Analyzer Tester Tool

Brief Introduction

BH-4AS 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.

Main features

• 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.

• CSTN colorful 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.
