VACUUM GAUGES, DIGITAL

  • Improved functionality within the navigation menu helps to save energy and to increase the life cycle of the battery.
  • Large, combined analogue and digital graphical display allows to detect tendencies and makes for easy and precise readout.
  • Convenient user-selectable pressure units in mbar, hPa or Torr.
  • Multiple vacuum connections and the addition of a support rod allows for convenient installation in almost every laboratory application.
  • Chemical resistant wetted parts together with the capacitive ceramic dia­phragm pressure sensor provide excellent long-term stability and accuracy.

The DVR 2pro is a fully electronic, versatile vacuum gauge for use in the measuring range from atmospheric pressure to 1 mbar. All wetted parts are made from enhanced chemical resistant materials which allows for the use under very arduous laboratory conditions. The high accuracy and the large graphical display from the DVR 2 have also been carried forward for the “pro” version. One of the main enhancements is the power supply which now comprises a regular 9V Alkaline battery. The new battery slot at the back of the gauge allows for easy replacement of the battery. A wider range of connection parts provide a great range of connection flexibility for laboratory use.
