Ideal for air outlets in cleanrooms: use the high-precision vane probe (with the compatible measuring instrument) to measure even the lowest air velocities and volume flows as well as the temperature. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.
