VD81

The versatile VD81 digital vacuum meter with data logger and USB interface measures absolute pressure in the rough vacuum range with a resistant Piezo sensor. Více 

Overview VD81 Piezo vacuum meter

  • Chemically resistant: Chemically resistant ceramic sensor with FKM sealing, suitable for rough industry environment
  • Robust: Insensitive against contamination
  • Fast: Adjustable min. logging rate of 50 ms for fast processes, e. g. for the area of vacuum packaging
  • Versatile: Gas-type independent measurement

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)
