The small diameter Bluetooth vane probe is to be used with the compatible Testo 440 multifunction measuring instrument to determine air velocity and volume flow. Measurements are transmitted to your measuring instrument via Bluetooth, up to 65 ft. 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.
