Testo 417-2 : Vane Anemometer
The optionally available testo vent 417 funnel set allows you to carry out measurements at ventilation grilles and disk valves. There is also an airflow 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, airflow speed, and 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 that allows you to compare the measurement you have just taken 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.
