Digital CH4 Gas Detector BH-90A Portable Methane Detector 0-100%LEL

Digital CH4 Gas Detector BH-90A Portable Methane Detector 0-100%LEL 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.   INTRODUCTION Gas Detected: combustible gas (CH4,C3H8,H2) and toxic gas, oxygen, Other rare toxic gas like ammonia, NO, PH3, NH3, NO2, HCN, SO2 etc also available,Can be specified by the Customer in advance. *Advanced MCU control with low power consumption; *Adjustable low and high alarm level; *Adjustable calibrating level; *High concentration protection for combustible gas; *Self test for the combustible gas sensor; *Low battery indication; *Self-adjustment function *Visual and audible alarm with vibration; *Advanced self-examination and self-renovation function *Password management to avoid wrong operation; *Explosive proof housing.
