Features

Details

  • Measures: 1) Airflow volume in cubic feet/minute (CFM) or cubic meters/minute (CMM); 2) Air speed; 3) Enthalpy (the heat of vaporization of air in an HVAC/R system duct); 4) Ambient temperature; 5) the dew point and wet bulb temperatures; 6) the Wind Chill Index (WCI); and (7) Relative humidity (RH)
  • Tracks Min/max/avg session values for air speed and airflow volume
  • Five available air speed units: ft./min, mph, m/sec, km/hr, knots
  • Airflow volume and Enthalpy readings are available in Imperial or metric units
  • Large backlit LCD
  • °F/°C switch
  • Auto power off
  • Vane and sensor protection cap
  • Tripod mount
