testo 417 vane anemometer with integrated 100 mm vane incl. temperature measurement,battery and calibration protocol The compact testo 417 anemometer with built-in flow/temperature vane Ø 100 mm to measure flow speed, volume flow and temperature. Volume flow is shown directly in the display. Accurate volume flow calculation thanks to easy input of duct area. In addition, it is easy to switch to the current temperature reading. The flow direction, i.e. drawn in or blowing, is visible in the display. Timed and multi-point mean calculation provide information on mean volume flow, flow speed and temperature readings. The optional funnel set facilitates efficient measurements at ventilator grilles and disc outlets. Min/max values can also be shown in the display. Current readings can be frozen in the display using the Hold function.
