Hot Wire Anemometer Accessory Head - Code : AAT3
The AAT3 is a Hot-Wire Anemometer & Psychrometer in one accessory head. Now HVACR professionals can measure air velocity, temperatures, and %RH all in one tool. When attached to a wireless transmitter, AAT3 measurements can be sent wirelessly to any Fieldpiece wireless meter (HG3, LT17AW, EH4W) from anywhere on the job site. So results can be read in real-time on your wireless meter from up to 30 mtrs away.
Telescopic 1-mtr probe for In Duct or Grille access
Measures temperatures, %RH, and air velocity
Calculates wet bulb and dew point
Automatically calculates Target Superheat, Target Evap Exit Temperature, and Total CFM (when using the Fieldpiece HVAC Guide System Analyzers)
Fast response time
Depth and direction indicators
Hands-free testing with stabilizing cone and magnetic hanger
Can send wireless measurements from up to 30metres away
