Vacuum Accessory Head - Code : AVG2

Most economical Vacuum Gauge for your tool kit. Displays pressure in microns in steps of 1 micron. Has pump down indication showing progress from atmospheric pressure. Use it with the Fieldpiece EHDL1 or multimeter with mVdc Ranges.

Two [2] Year Warranty


  • Auto off can be disabled for data logging with DL3
  • Straight access to sensor for easy cleaning
  • Brass "T" piece for inline vacuum testing.
  • LEDs indicate INCreasing, DECreasing and STABLE vacuum

  • Fitting: Standard 1/4 flared brass fitting (male)
  • Conversion rate: 1 mVDC/1 micron of mercury
  • Range: 50 to 2000 microns of mercury
  • Resolution: 1 micron of mercury
  • Accuracy: +/-10% or +/-10 microns, (50 to 1000 microns) @ 73F 9F (23C 5C), <90%RH.
  • Operating environment: 32 to 122F (0 to 50C) @ <75%RH
  • Storage environment: -4 to 140F (-20 to 60C) @ <80%RH with battery removed
  • Pump down indication: When pumping down from atmospheric pressure to 2000 microns, output of head goes from over 3VDC to 2VDC.
  • Overload: 500psi (3400kPa)
  • Battery: 9V
  • Battery life: 35 to 40 hours typical (alkaline). Red LED indicates battery is below operating level.
