Toxic Gas Detector BH-4S multi gas detector high accuracy cl2 so2 co gas monitor system
product description
The BH-4S four-in-one gas detector detects natural gas concentration by 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, 320 * 240 HD interface screen resolution, with loaded computer analysis, Chinese and English switching and other ancillary functions, the machine meets the national standards of metering production license. A fundamentally safe instrument that continually detects the concentration of toxic, dangerous, flammable and explosive gases in the work environment. It is suitable for protection against explosions, toxic gas leakage and rescue, underground pipelines, mining, metallurgy, power plants, chemical industry, tunnels, tunnels, etc., effectively preventing the occurrence of poisoning accidents, ensuring that life and workers' safety is not compromised, and production equipment is not damaged.

Advantage
Curve display: Can display changes of different gas concentrations of a period of time, to help observe and analyzer date
Alarm methods:indicate alarm by sound,light,vibration,and curve display in different colors,User can set high low alarm point according to actual need.
USB date transmission interface:By installing our software,user can upload records to computer, which makes it easier to do analysis.
International certification:ATEX,KA.MA,CNEX,CE,SIL
