testo 410-2 - Pocket sized Vane anemometer

Special Price 0.00


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.

  • Measurement of air velocity, air temperature and humidity

  • Pocket sized handy anemometer with a permanently installed vane

  • Calculates dew point and wet bulb temperature, wind chill and Beaufort wind force

  • Includes single-point averaging, max/min values and Hold function


Product Description

With its handy format, pocket sized vane anemometer testo 410-2 is extremely suitable 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 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 anemometer 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.

The anemometer offers useful accessories and functions

We have equipped the vane anemometer with a clip-on protective cap. This offers reliable protection if you are not using testo 410-2 straight away. During the measurement you can use the fitted wrist strap, which prevents the anemometer from falling.

Take a look at the useful functions offered by the anemometer testo 410-2:
Single-point averaging: calculation of the mean air velocity, for example at ventilation grilles (air outlets)
Hold function: enables the current measurement data relating to air velocity, humidity and air temperature to be recorded and compared with each other
Max/min values: displays the minimum or maximum values since the vane anemometer was last switched on or reset
Illuminated display: read off your readings quickly and easily, even if visibility is poor
Selectable units: air velocity: m/s, km/h, fpm, mph, kts and Beaufort; air temperature: °C, °F and wind chill; humidity: relative humidity, wet bulb and dew point temperature
