More applications, less equipment: if you already own one of our probes with a universal handle, you can easily expand your portfolio of probes with the high-precision 100 mm vane probe head.

Ideal for air outlets in cleanrooms: use the high-precision vane probe (with the compatible measuring instrument) to measure even the lowest air velocities and volume flows as well as the temperature. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.

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, e.g. at draughty windows.

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

With the Testo Smart Probes VAC set, you can check air velocities, humidity, volume flows and temperatures in, on and around air conditioning systems. The robust testo Smart Case enables the measuring instruments to be conveniently transported and ensures that they are always to hand when needed.

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.
