Pirani, 100-5e-4 mbar, metal sealed, DN16KF USB-interface


The versatile VD83 Pirani vacuum meter with data logger and USB interface measures absolute pressure in the fine vacuum range

Overview VD83 Pirani vacuum meter:

  • Long-lasting: Pirani sensor with durable, elastic helix filament
  • Stable: Measuring values are stable due to optimized temperature compensation
  • Well protected: Integrated metal facing protects the sensor against contamination like oil vapours or solvent vapours
  • Useful: Gas type correction factors for immaculate pressure readings
  • UHV suitable: Suitable for ultra high vacuum applications due to metal sealed stainless steel measuring cell (He leakage rate <5e-10 mbar l / s)

Overview VD8 vacuum meters:

  • Variable: VD8 compact vacuum meters can be used as a portable instrument or for permanent installation in vacuum facilities. The gauges can be operated by a battery or a plugin power supply
  • Data logger: Integrated data logger for up to 2000 measurement values
  • Flexible connection: VD8 vacuum meters can be placed directly into a vacuum chamber, connected to an appliance with their flange or with a suitable adaptor
  • Min/Max memory function: Storage of minimum and maximum pressures achieved during measurement
  • Long battery livetime: Due to cycled measurements, the compact vacuum meter reaches a high battery lifetime; the user can choose between automatic switch off (time adjustable) for battery saving or continuous operation
  • Pressure units: mbar, Torr, hPa
  • Data export: USB interface for easy push button data transfer to PCs, but no PC connection is necessary during measurements
  • VacuGraphTM Windows Software: To visualize, analyze and save measurements on a PC (lite version free of charge)
