Compact Vacuum Meter / Data Logger Absolute Pressure 100 to 5 x 10-4 mbar VD83 precision digital vacuum meter measures absolute pressure in the fine vacuum range. It is available with USB interface and can be used as data logger. The VD83 can be operated with either battery or external power supply making it ideal for portable or fixed applications. Typical Applications • Checking and setup of vacuum appliances • Temperature compensated, metal sealed Pirani sensor with durable helix filament • User friendly operational concept • High accuracy • Easy configuration of the vacuum meter by VacuGraphTM software or directly at the instrument • Diagnosis and documentation of rotary vane vacuum pumps • Service and maintenance • Excellent repeatability • Modern teaching aid with PC interface • The sensor is well protected against condensed solvents • Recording and plotting of pump down diagrams • High battery life due to clocked measurement • Leak tests • Compact, user-friendly • Vacuum centrifugation • Pressure units mbar, Torr, hPa • Coating plants • Min/Max memory: Storage and display of high and low values • Gas correction factors for correct pressure readings • Precise push button readjustment • Measuring rate of the data logger can be arbitrarily set by means of VacuGraphTM software or directly selected at the instrument • Online data transfer to PC via USB • Data logger functionality: Save up to 2000 measurements in the vacuum meter and push button data transfer to a PC; no PC connection is necessary during the measurement • VacuGraphTM software for saving and plotting measurements on PC • Battery conserving auto-off mode or continuous operation Actual Pressure
