TESTO 417 Large Vane Anemometer

Features: Hold button freezes readings Auto Off Built-in 4 inches vane Flow direction is shown in display Flow, volume flow ( cfm) , and temperature measurements Multi-point and timed mean calculations Max-Min values Auto Off function Clear backlit display Soft carrying case The compact testo 417 anemometer utilizes a fixed flow temperature vane to directly measure flow, volume flow and temperature.Volume flow is shown directly on the clear backlit display. Just input the duct measurements, and accurate volume flow calculations are automatically displayed. You can also switch between flow and temperature.Flow direction, either from pressure or vacuum source, is visible in the display.Timed and multi-point mean calculations provide information on mean volume flow, velocity and temperature.The optional funnel set facilitates efficient measurements at ventilator grilles and disc outlets.Min-Max values can also be displayed. The " Hold" function freezes current readings in the display making data recording easy.
