Introduction
BH-90 is a high-performance portable single Gas Detector, using the mainstream 8-bit micro-control technology, fast response, high measurement accuracy, good stability and repeatability, simple operation. Compact and highly waterproof, it can withstand harsh environments. Comes with a flashlight for temporary work in the dark. Built-in 1500mA large-capacity rechargeable lithium battery, ultra-long standby, 12864 dot matrix LCD screen can display various technical indicators and gas concentration values, can view historical alarm data, and has data storage function. It is suitable for explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industries, tunnels, tunnels and other places, effectively preventing the occurrence of poisoning accidents and ensuring that the life safety of staff is not violated. There is no loss of production equipment.
