Flow meters

The testo 420 differential pressure measuring instrument is suitable for accurate differential pressure measurement up to 120 Pa, e.g. when checking filters in HVAC systems.

Flow velocity measurement by impeller incl. Impeller, Ø 100mm 1 ... 35 m / s, accuracy 0.25 ... 3m / s ± 0.1 m / s

Make sure you get the volume flow measuring hood testo 420 for larger ceiling outlets and benefit several times in the maintenance of HVAC

With the hot wire anemometer testo 405 i measure air velocities, temperatures and flow rates. Via Bluetooth, the readings radioed directly to the testo

testo 410-1 misst Luftgeschwindigkeit und -temperatur. Durch die integrierende Messung mit dem 40 mm-Flügelrad ist es ideal geeignet für schnelle Spotmessungen am Luftauslass. Eine zeitliche
