Compact Vacuum Meter / Data Logger Absolute Pressure 100 to 1 x 10-3 mbar VD84 digital Pirani vacuum meter with exchangeable sensor head reads absolute pressure in the fine vacuum range. It is available with USB interface and can be used as data logger. VD84 can be operated with either battery or external power supply making it ideal for portable or fixed applications. Typical Applications • Monitoring of vacuum insulations • External detachable sensor with stainless steel small flange DN 16 ISO-KF or 1/8"NPT male thread • Evacuation of brake and air-conditioning systems • Checking and setup of vacuum appliances • Operational control and documentation of vacuum plants and pumps • Service and maintenance • Modern teaching aid with PC interface • Recording and plotting of pump down diagrams • Temperature compensated Pirani sensor with durable helix filament • Excellent reproducibility • The sensor is well protected against condensed solvents • Long battery life due to clocked measurement • Compact, easy to use • Leak tests • Pressure units mbar, Torr, hPa • Vacuum centrifugation • Coating plants • Min/Max memory: Storage and display of high and low values • Vacuum evaporators • Precise push button readjustment • USB interface • Easy configuration of the vacuum meter by VacuGraphTM software or directly at the instrument • Measuring rate of the data logger can be arbitrarily set by means of VacuGraphTM software or directly selected at the instrument • Gas correction factors for correct pressure readings • 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 Actual Pressure • Automatic switch off or continuous operation • User friendly operational concept
