OC-905 Portable Ammonia NH3 gas detector with inner pump

portable gas detector


Description:

OC-905 Portable NH3 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 Ammonia 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, Poultry house, etc., where need to inspect the NH3 gas concentration.



portable gas detector
