Use this 4 inch high precision 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 65 ft.. Includes temperature sensor.

Use this 4 inch wired high precision vane probe with the compatible testo 440 multifunction measuring instrument to measure air velocity, volume flow and temperatures up to +158°F. Includes temperature sensor, fixed cable.

Intuitive technology provides a parallel determination of air velocity, volume flow, and air temperature. Precisely detects the smallest of air velocities from as little as 0.1 m/s, making it ideal for laminar flow measurements in cleanrooms.

Use the 100 mm vane/temperature probe to determine flow velocity and volume flow at ventilation outlets. Integrated temperature measurement enables the vane anemometer to measure temperatures up to +60 °C.
