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
