The DVR 2pro is a fully electronic, versatile vacuum gauge for the measuring range from atmospheric pressure to 1 mbar. All wetted parts are made from enhanced chemical resistant material which allows the use under very rough laboratory conditions. The large, graphical analog display with digital measuring values allows to detect tendencies and makes it easier to readout precisely. One of the main enhancements is the power supply with a normal 9 V alkaline battery. The battery slot at the back of the gauge allows for easy replacement of the battery.
- Improved functionality within the navigation menu helps to save energy and to increase the life cycle of the battery.
- The large graphical display offers a good visualisation and precise reading of the values.
- Pressure unit user-selectable in mbar, hPa or Torr prevents unnecessary conversions. Different vacuum connections and the additional support rod allow the use in almost every laboratory application.
- Chemical resistant materials for wetted parts together with the capacitive ceramic diaphragm pressure sensor provide excellent long-term stability and accuracy.
Vacuum gauge complete with integrated vacuum sensor, including battery 9 V alkali-manganese, support rod, connecting parts and manual.
