Fieldpiece - Hot-wire Anemometer | AAT3

The In-Duct Hot-Wire Anemometer & Psychrometer accessory head, AAT3 allows HVACR professionals to measure air velocity, temperature, and %RH all in one tool. The engineered 38" telescoping probe with laser etching and quick-response sensor provides quick and easy airflow measurements from the correct location--near the evaporator. When using with the Fieldpiece HVAC Guide System Analyzers, the AAT3 can automatically calculate target super heat and target evaporator exit temperature. Connected to a wireless transmitter, the AAT3 can send measures wireless to any Fieldpiece Wireless Meter (HG3, LT17AW, EH4W) up to 100' away.
