The VF-mk2 communicates via Bluetooth with a smartphone or tablet using an app. In the user-friendly app measurement projects can be created. The measurement of multiple dwellings is easy: create all valves for one dwelling and copy them to the next one. A measurement takes less than 10 seconds after which a measurement report can be sent from your phone. The VF-mk2 has a patented flow straightener to guarantee accurate measurements on a large collection of different supply and exhaust grilles. Measuring range is 10 to 100m3/h, accuracy 3..5m3/h.
