Multi Gas Detector 4 Gas Detector LCD Screen Backlight Rechargeable
Battery Sound Light Alarm 4 in 1 Gas Analyzer
Brief Introduction:
The BH-4S four-in-one gas detector detects the gas concentration by
natural diffusion method. It adopts the latest 32-bit
microprocessor and imported industrial grade sensor, which has fast
response time, high measurement accuracy, good stability and
repeatability. 2.4-inch LCD screen, resolution 320*240 HD interface
display, with upload computer analysis, Chinese and English
switching and other auxiliary functions, the machine meets the
national measurement production license standards. An intrinsically
safe instrument that continuously detects the concentration of
toxic, hazardous, flammable and explosive gases in the working
environment. It is suitable for explosion-proof, toxic gas leakage
and rescue, underground pipelines, mines, metallurgy, power plants,
chemical industry, tunnels, tunnels, etc., effectively preventing
the occurrence of poisoning accidents, ensuring that the lives and
safety of workers are not infringed, and the production equipment
is not damaged.
