Hot Wire Anemometer with Temperature

STA2 In-Duct Hot Wire Anemometer is a great alternative to costly bulky hoods.  With ease, techs can input free area, and the STA2 automatically averages multiple test points and continually calculates and displays CFM or cubic meters\sec & litres\sec.

 



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.

Features

  • 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
