OC-905 Portable CO gas detector designed with the inner pump and
the famous brand sensors, with stable performance and high
accuracy. Used to detect the single gas concentration for the
Combustible gas, Toxic gas, Carbon Dioxide, Oxygen, TVOC, etc. It
can directly display the gas concentration data on the screen, the
data also could be exported to the computer by USB cable.
For the portable Carbon Monoxide gas detector, the common
applications is gas safety inspection and alarm for industrial
scene, such as petroleum refinery, chemical plants, LPG stations,
boiler rooms, gas stations, paint spray booths, metallurgy, mining,
fire, environmental protection, etc., where need to inspect the
Carbon Monoxide CO gas concentration.
Used the original imported sensor, semiconductor technology of
ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip,
so with the high accuracy.
2.5 inch dot matrix display interface.
All English operation menu and easy operation.
Unit data available for ppm and mg/m3.
The circuit installed the four layers of wire, so well
Explosion proof grade is Exd ib ⅡC T4 Gb.
Inspect the gas concentration and alarm when it reaches preset
High accuracy, good stability and good repeatability, long working
One-key operation to restore to factory default setting.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
The built-in pump could be controlled.
