Composite gas detector

QRAE II is a can detect a variety of toxic and harmful gas portable four in oneinstrument, can detect gas, oxygen and toxic gases.
QRAE II compatible diffusion and pump two kinds of work mode, suitable for different applications. The instrument has the advantages of small volume,convenient operation, built-in Chinese menu, more suitable for China users.Design of humanized turn display screen, convenient for observation.
QRAE II can be installed at the same time several sensors detect:
Sensors detect the combustible gas catalytic combustion
Electrochemical sensor for detection of hydrogen sulfide, carbon monoxide and other toxic gases (SPE) solid electrolyte oxygen sensor detection, more stable than life longer, the traditional performance of electrochemical sensors
