Hot-wire Anemometer
DQG3V\FKURPHWHULQ2QH
The AAT3 InDuct Hot-wire Anemometer and Psychrometer gets into ducts easily for
measurement of temperatures, %RH, and air velocity.
ce HVAC Guide® System Analyzer’s
These measurements go hand in hand with the Fieldpiece
Superheat, TEET, CheckMe!, and CFM switch positions for faster, more accurate and
convenient diagnostics.

The STA2 InDuct, Hot-wire Anemometer calculates CFM from
air velocity and free area. Averaging air velocity from several
measurements and inputting free area are a snap.
With in-duct traversing it’s an excellent alternative to costly, bulky
hoods for air balancing.

Now you can get in-duct wet bulb and dew point measurements
in the convenience of a Fieldpiece Accessory Head.
Not only does the ARH5 make it easy to get in-duct measurements
near the evaporator, but now techs can get wireless indoor
wet bulb measurements in real-time, while they are making
