Combustible Gas Detector combustible gas indicator 4 in 1
combustion gas detector
product description
BH-4S portable compound gas detector is used for rapid detection of
various gas concentrations, high measurement accuracy, good
stability, small size, light weight, waterproof, dustproof,
explosion-proof, LCD adopts advanced circuit design, mature kernel
algorithm Processing, unique shape design, obtained a number of
patents such as software works and appearance. The machine is
suitable for detecting gas concentration in pipelines or in
confined spaces and atmospheric environments; gas leakage. More
than 500 kinds of gas are detected.
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
