The Series AP2 Wireless Thermo-Anemometer Probe measures air velocity, air flow, and temperature when combined with the Model UHH2 Universal Handheld. In order to prevent damage to the sensing element, the probe has a protective sleeve that slides over the sensor when it is not in use. Markings on the probe allow users to know the insertion depth to obtain better accuracy when traversing the duct.
Wireless probes can take measurements up to 50 feet away from the UHH2. A bicolor LED flashes on the handle of the probe to indicate communication status with the UHH2. The battery is rechargeable via the mini-USB connector on the bottom of the probe.
