    Product Description

    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.

    Designed specifically for HVACR professionals, the AAT3 In-Duct Psychrometer is a great tool to properly install and service fixed restrictor systems.  More than 70% of A/C units are running inefficiently, but with the AAT3 it's easier to ensure units are running at their maximum efficiency. HVACR pros can trust the results for tests like temperature splits, target evaporator exit temperature, target superheat, and CheckMe!® because measurements are taken near the evaporator without the interference of outside air temp or leaks in the duct work.
