Use this 4 inch wired vane probe with the compatible Testo 440 multifunction measuring instrument to measure air velocity, volume flow and temperatures up to +158°F. When connected to the 440 Air Velocity and IAQ meter (Sold Separately), clearly structured measurement menus for volume flow enable the measuring instrument to be operated intuitively. The volume flow is precisely calculated thanks to a convenient input feature of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument. Pressing the button on the vane probe is a particularly useful feature to operate the measuring instrument. For example, to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time, just tap the button to begin and end the measurement. This probe also includes a built in temperature sensor.
