BH-90A portable single gas detector can make continuous detection to combustible and toxic gases. It is suitable for combustible and toxic gas leakage detection in underground pipe or mines, and keeps the workers safe, prevents the facilities from being destroyed.The detector, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and reproducibility. The detector adopts embedded MCU controller, easy to operate.
The shell adopts special high strength material and anti-smooth rubber, with the characters of water-proof and dust-proof.
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.
