Description

testo 417 – Air flow meter
Wöhler from Germany

The testo 417 vane anemometer allows you to carry out quick and precise measurements at air inlets and outlets. The easy-to-read display shows air flow speed and direction as well as volumetric flow rate and temperature. The meter can also calculate the mean time value, average value and minimum and maximum value at the touch of a key.

    • Compact anemometer with integrated 100 mm vane
    • For measuring air flow, volumetric flow rate and temperature
    • Ideal for carrying out measurements at air inlets and outlets
    • For carrying out measurements at disk valves, ventilation grilles and ceiling diffusers using optionally available accessories

Product Description
The testo 417 vane anemometer allows you to measure air flow speed, volumetric flow rate and temperature simultaneously. The integrated vane makes it ideal for carrying out measurements at air inlets and outlets.
The optionally available testovent 417 funnel set allows you to carry out measurements at ventilation grilles and disk valves. There is also an air flow rate rectifier for carrying out quick and reliable measurements at diffusers.

The vane anemometer is designed to provide you with the following values
The easy-to-read display shows all important data including air flow direction – ie. whether the air is being sucked in or blown out – air flow speed and the volumetric flow rate as well as the actual temperature.
The mean time value and average value provide you with information regarding the average volumetric flow rate, air flow speed and the temperature measurement. In order to carry out the volumetric flow rate simply enter the area of the duct or use the optionally available funnel set.
In addition, there is also a hold function which allows you to compare the measurement you have just take with previous measurements. Min and max values are also available at the touch of a key. And thanks to the testo 417’s backlit display you can read the measurements in the dark or in poor lighting.
