The High-Precision Vane Probe (Ø 100 mm, Digital) with Bluetooth® is designed for precise airflow diagnostics in cleanrooms, laminar flow environments, and air outlets, even at very low air velocities starting from just 0.1 m/s. It measures air velocity, volume flow, and temperature in parallel and transmits readings wirelessly to the compatible Testo multifunction measuring instrument (sold separately), making it ideal for ceiling installations and locations with limited accessibility.

The probe features a clearly structured measurement menu and smart Bluetooth connectivity for intuitive operation. A practical button on the handle allows for storing individual readings or managing measurement series directly at the probe.

With a universal modular handle system, optional extendable telescope with a 90° angle, and accessories like the testovent 417 funnel set and volume flow straightener, this probe adapts flexibly to a wide range of applications while minimising the need for additional equipment.

Only the probe head needs calibration, ensuring minimal instrument downtime thanks to the intelligent calibration concept.
