Top kwaliteit - alles zit er bij :-)

Dit is echt een prima gebruiksklare set. Er zit zelfs een batterij bij. Heel handig dat alles in een koffertje geleverd wordt. Dan heb je altijd de complete set bij elkaar en raakt er niks kwijt. Het is een degelijk apparaat. Goed display. Gemakkelijk te gebruiken. Er zit een duidelijke handleiding bij.

Seems to work very well for a mechanical device.

I’m not a pro, so probably don’t have enough knowledge to evaluate this device fully, but it seems to serve its purpose very well. The handheld sensor (impeller) is lightweight and very low friction. Doesn’t take much air movement to spin it and register a flow rate. Often times I won’t even use the digital console when I’m just looking to see if I have some air flow or nothing. There’s plenty of modes and features in the digital console, but I only use the most basic ones. There’s plenty carrying and storage case is nice to have as I don’t use it much.
