Use the testo 405 thermal anemometer to measure air velocity, volumetric flow and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts and for measuring the air velocity in rooms for indoor air quality, e.g. at draughty windows.

With the testo 405i hot wire anemometer, you can measure air velocities, temperatures and volume flows. Via Bluetooth, the readings are transmitted wirelessly straight to the testo Smart App on your smartphone or tablet. You can view the values conveniently and use numerous intelligent features:

The testo 410-1 vane anemometer measures air velocity and air temperature. You can use it to carry out quick spot measurements at ventilation grilles (air outlets). The anemometer is also ideal to use outdoors. It displays the units m/s, km/h, fpm, mph and kts, and also calculates wind chill and the Beaufort wind force.

Ideal anemometer for air velocity measurement at ventilation grilles (air outlets) and for inspecting air conditions – also outdoors. Pocket sized testo 410-2 also measures humidity and air temperature. The anemometer can also accomplish the calculation of parameters such as dew point and wet bulb temperature, wind chill or Beaufort wind force – all at the touch of a button.

Professional measuring technology in a small format: the compact testo 410i vane anemometer with smartphone operation measures the volume flow, air velocity and temperature at air outlets quickly and reliably. The testo Smart App enables readings to be viewed conveniently and offers intelligent additional functions.

For air-conditioning engineers: Compact kit containing four measuring instruments for your most important measuring tasks in, on and involving air conditioning systems. The testo&nbsp;Smart App enables you to work more easily and efficiently: Use intuitive measurement menus for volume flow measurement, for automatic calculation of the dew point and wet bulb temperature or for detecting areas susceptible to mould according to the traffic light principle. Measurement data reports can be emailed directly as a PDF or Excel file.

This certificate documents the ISO calibration of your anemometer or Pitot tube. Calibration is carried out at the measuring points 5 and 10 m/s.
