4 in 1 Multi-gas detector
Type: DX-BH-4S
Introduction
The DX-BH-4S portable multi-gas detector is used to detect the gas concentration by natural diffusion, using the latest 32 bit microprocessor and imported industrial grade sensor. The response time is fast, the measurement accuracy is high, and the stability and repeatability are good. 2.4 inch LCD screen, resolution 320*240 high definition interface display, with computer analysis, Chinese and English switching and other auxiliary functions, the whole machine meets the national standard of measurement production.
It can continuously detect the concentration of toxic, harmful, flammable and explosive gases in the working environment. It is suitable for explosion protection, toxic gas leakage and emergency rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels and other places. Effective prevention of poisoning accidents, ensuring the safety of workers is not infringed, and production equipment is not damaged.
