OC-905 Portable pump suction Nitric Oxide NO gas detector

OC-905 Portable pump suction Nitric Oxide NO gas detector


OC-905 Portable Nitric Oxide 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 NO gas. 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 Nitric Oxide 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 NO gas concentration.
