Chụp đo tốc độ gió testo 420
Light, precise and convenient: the testo 420 flow capture hood makes volume flow measurement at larger air inlets and outlets considerably easier. At only 2.9 kg, it is the lightest volume flow hood on the market. And with its integrated flow straightener, the measuring device for volume flow measurement sets new measuring precision standards at swirl outlets. This allows users to fulfil hygiene guidelines and requirements for indoor air quality and volume flow in ventilation and air conditioning systems quickly and precisely, e.g. in industry, office areas or cleanrooms.
