Model VP3 100 mm Vane Thermo-Anemometer Probe

Wireless, Measures Velocity, Flow, Humidity, and Temperature

The Model VP3 Wireless 100 mm Vane Thermo-Anemometer Probe measures air velocity, air flow, humidity, and temperature when combined with the Model UHH6 Universal Handheld. By having a larger diameter, the rotating vane is able to measure velocities down to 50 fpm or 0.25 m/s. An arrow is molded into the vane housing to depict the flow direction.

These probes use a Bluetooth Low Energy (BLE) signal for effortless connection and low power consumption. Wireless probes can take measurements up to 50 feet away from the UHH6 or compatible handheld. A bicolor LED flashes on the handle of the probe to indicate communication status with the handheld device. The battery is rechargeable via the mini-USB connector on the bottom of the probe.
