BH-90-EX

Gas Detector

Introduction

BH-90 is a cost-effective portable single Gas Detector, which adopts the mainstream 8-bit micro-control technology, with fast response, high measurement accuracy, good stability and repeatability, and easy operation. Small in size and highly waterproof, it can stand the test of harsh environments. It comes with a flashlight, which is convenient for temporary operations in dark environments. Built-in 1500mA large-capacity rechargeable lithium battery, long standby time; 12864 dot-matrix LCD can well display various technical indicators and gas concentration values, and can view historical alarm data, and has data storage function. It is suitable for explosion-proof, poisonous gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels and other places. It can effectively prevent poisoning accidents and ensure the safety of staff. Production equipment is not subject to loss.
