Works great for HVAC balancing, optimization and data gathering. Bearings are good and very low friction.

Worked on supply side and exhaust side to know how much you’re getting air. L” x W” = answer divided by 144 and that where you get area.

Easy to use and works well. Great price.

Das Gerät tut was es soll, grosse Anzeige und die Bedienung wie Handhabung ist einfach.Sehr praktisch ist die mitgelieferte Tasche.

The delivery was excellent, arrived the very next day. Well packaged and wrapped, The unit has a nice clear display and the back light really inhance's the display. The useful feature is having the vane on a cable, I have used other units with a integrated vane which can be problematic if the the grill or whatever you are measuring is above you which makes reading the display awkward. The average faclillity is another useful feature as I have had to take multiple readings write them down and work out the averages myself. This unit can do it for you but the results are only displayed for a short time, it would have been nice to have the ablity to hold the result on the screen. The build quality is not bad, a little plasticity but not bad. The back stand however is really flimsy and I can't see it holding upto continued use. I have a multimeter made by extech and the back stand is far more substantial even though it is plastic. The unit comes with a carry case with additional shoulder strap which is a nice touch. It is the basic nylon type of matirial which is not the best but certainly good enough. I haven't fully used the unit yet but first impressions are good. All in all not a bad unit for the price there are cheaper out there but I wanted a unit made by someone I have heard of, as I mentioned I have a multimeter and it has served me well and the company I work for is actually buying four of the multimeters.
