With its handy format, our testo 410-2 vane anemometer is extremely practical for quick control measurements on ventilation grilles and in the outdoor area. With the built-in impeller (diameter 30 mm) you can already measure low air speeds from 0.4 m/s to 20 m/s. To check the air conditions, the anemometer is equipped with our long-term stable Testo humidity sensor and with an NTC -Temperature sensor with a measuring range of -10 … +50 °C. This allows you to reliably measure air temperature and humidity. At the push of a button, the testo 410-2 displays additional parameters: the dew point and wet bulb temperature (wet bulb) as well as the Beaufort wind force and the wind chill temperature. The latter is the temperature felt by humans due to wind-related cooling. The vane anemometer is equipped with a protective cap that can be attached. It offers reliable protection when you are not using the testo 410-2. Use the attached hand strap during the measurement, it prevents theMeer tonenMinder tonen
