0635 9431

0635 9431 is a vane probe ø 100mm with Bluetooth including temperature sensor. Use this 4" vane probe with the compatible Testo 440 multifunction measuring instrument to measure air velocity, volume flow and temperatures up to +158°F. Measurements are transmitted to your 440 meter via Bluetooth, up to 65ft. When connected to the 440 air velocity and IAQ meter clearly structured measurement menus for volume flow enable the measuring instrument to be operated intuitively. The volume flow is precisely calculated due 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.

• Measuring range from -20 to +70°C(temperature - NTC), 0.3 to 35m/s(velocity / volume flow)
• Dimension is 375 x 105 x 46 mm
• 4 x type AA batteries
