product description

Testo 417 impeller anemometer can simultaneously measure wind speed, air volume and temperature with integrated impeller probe, ideal for air inlet and outlet measurements.
The optional testovent 417 air volume hood kit helps testo 417 - the impeller winds to better detect the air volume at the grille outlet and damper. The built-in grille area correction factor ensures accurate completion of the grille tuyere Determination of wind speed and air volume.

Testo 417 - Impeller Anemometer can provide you with the following data

The clear, easy-to-read display shows all the important parameters, including wind speed, volume, volume flow, and real-time temperature.

All readings, including wind speed, air volume and temperature, can be displayed as current values ​​or as averages testo 417 - Impeller Anemometer allows accurate calculation of volumetric flow rates by simply entering the cross-sectional area of ​​the pipe or using an optional air volume enclosure.

At the same time, hold down the key to maintain the reading, so that you just measured the measured data and the previous comparison, the key to display the maximum / minimum value testo 417 - impeller anemometer display with backlight , To help you in the lighting conditions even harsh environment can also clearly read the data.
