Portable NO2 Gas Detector Meter Nitrogen dioxide Detector Tester BH-90A 0-20ppm

Description

Portable NO2 Gas Detector Meter Nitrogen dioxide Detector Tester BH-90A 0-20ppm
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.
