Handheld multi gas detector SO2 sulfur dioxide detector with ATEX
certificate
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.
