  testo 417, digital anemometer with 100 mm vane diameter

  Includes factory calibration protocol and 3 AA batteries

  The compact testo 417 anemometer with a built-in 100 mm vane for measuring air velocity and temperature is designed for determining flow velocity, volumetric flow, and temperature. The volumetric flow is displayed directly on the screen. Accurate calculation of volumetric flow is ensured by the easy alignment of the probe with the air duct. In addition, it is easy to switch to the display of the current temperature. The flow direction (e.g. supply or exhaust) is shown on the display. The averaging function over time and number of measurements allows obtaining averaged values of volumetric flow, air velocity, and temperature. An optional funnel set enables efficient measurements at ventilation grilles, round ceiling diffusers, and plate air valves. Min/max values can also be displayed. The Hold function allows you to freeze current measurement data on the display.
