VD83 – Digital Compact Vacuum Meter / Data Logger

Absolute Pressure 100 mbar to 5 x 10-4 mbar (=hPa), 75 Torr to 5 x 10-4 Torr

VD83 digital vacuum meter measures absolute pressure in the fine vacuum range. It is equipped with USB interface and can be used as data logger (save up to 2000 measurements).
The VD83 can be operated with battery or external power supply making it ideal for either portable or stationary applications.


  • Temperature compensated, metal sealed Pirani sensor with durable helix filament
  • High accuracy, excellent repeatability
  • Min/Max memory: Storage and display of high and low values
  • Gas correction factors for correct pressure readings
  • High battery life due to clocked measurement
  • The sensor is well protected against condensing solvents
  • Pressure units: mbar, Torr, hPa
  • Battery conserving auto-off mode or continuous operation

Typical Applications

  • Check and setup of vacuum appliances
  • Diagnosis and service of vacuum pumps
  • Coating plants
  • Evaporators
  • Leak tests and monitoring of vacuum insulations
  • Speed vacs
  • Recording and plotting of pump down diagrams
