Detector Description
Pump Single Gas Detector designed with the inner pump and advanced sensors, with stable performance and high accuracy. Used to detect the single gas concentration (Any gases can be customized ). 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 gas detector, the common applications are gas safety inspection and alarm for the industrial scenes, such as petroleum refineries, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, metallurgy, mining, fire, environmental protection, etc.,
