BH-90 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.
