Description:
OC-905 Portable Helium He gas detector designed with the inner pump and the famous brand sensors, with stable performance and high accuracy. 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 He 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 Helium He gas concentration.
