With its handy format, our testo 410-2 vane anemometer is extremely practical for fast check measurements at ventilation grilles and outdoors. With the permanently installed vane (diameter 30 mm), you can even measure low air velocities from 0.4 m/s to 20 m/s.
The anemometer is equipped with our Testo humidity sensor featuring long-term stability and with an NTC temperature sensor with a measuring range of -10 to +50 °C for inspecting the air conditions. You can therefore use this to measure air temperature and humidity reliably. The testo 410-2 displays other parameters at the touch of a button: the dew point and wet bulb temperature as well as the Beaufort wind force and the wind chill temperature, which is the temperature perceived by a person due to wind-related cooling.
