V&F AirSense

The V&F AirSense is a gas analyzer built around a mass spectrometer that uses the patented ion-molecule reaction (IMR-MS) principle. It is the multi-purpose model in the V&F range, intended for applications that involve an unlimited number of gas components and that call for maximum flexibility and robustness.
