There are different designs of the air flow meter. It is also available as an anemometer and can be used in a variety of areas. There are thus some sectors, particularly in the industrial field, where air flow measurement plays an important role. In addition to duct measurement, these also include outlet measurement and filter measurement. Whether you use a vane anemometer or a volume flow hood as a air flow meter is dependent on the conditions. It is all the more important for you to have a look at the individual instruments for air flow measurement and to decide which of the models best meets your expectations.
The air flow meter is a great help in these areas:
- duct measurements
- outlet measurements
- comfort level measurements
- filter measurements
- Measurement of air velocity, volumetric flow and air temperature
- For measurements in ventilation ducts and in rooms
- Particularly precise in the range between 0 and 2 m/s
- Telescope extendible to 300 mm
- for measuring volume flow, air velocity and temperature
- Simple configuration of the dimension and geometry of the duct cross-section for determining the volume flow
- Convenient for working in ventilation ducts thanks to its telescopic tube, which can be extended up to 400 mm
- Really convenient to operate thanks to the testo Smart Probes App (e.g. easy viewing of readings, measurement data trend, log function)
- Vane anemometer with permanently installed 40 mm vane
- Measurement of air velocity and air temperature
- Calculates wind chill and the Beaufort wind force
- Practical: with single-point averaging, max/min and Hold function
- Measurement of air velocity, volume flow and temperature
- Display of the volume flow of multiple outlets in order to adjust systems
- Easy parametrization of the outlet (dimension and geometry)

For measuring flow velocity
-
Ideal for high flow velocities and heavily contaminated flow
Use the robust, 1000 mm long Pitot tube with a diameter of 7 mm for measuring flow velocity (in combination with a compatible measuring instrument / probe).
The compact hot wire anemometer testo 425 with telescopic probe is ideal for simple, fast and precise determination of flow velocity and volume flow in ventilation ducts of air conditioning and ventilation systems. The connection to the testo Smart App enables configuration, display (also as second screen) and storage as well as documentation of the measurement directly in the App.
