Compact Vacuum Meter ● Piezo/Pirani ● 1200 to 5e-4 mbar
The versatile VD85 digital vacuum meter with data logger and USB interface reads pressure over 7 decades in the rough and fine vacuum range.
Its sensor combination of piezo and Pirani guarantees high resolution and precision over the whole range.
Maintenance of Vacuum Pumps
Systematic maintenance and servicing of vacuum pumps helps to prevent breakdowns in production and improves the availability of the system.
For diagnosis of the pump as well as for executing maintenance work the achieved minimum pressure and the pump-down characteristic have to be recorded. These factors provide essential information about the actual condition and performance of the pump.
A VD85 with wide range combination sensor is capable of capturing the minimum pressure of many pump types like diaphragm, scroll or rotary vane pumps. In addition the instrument can measure and –on demand- record the complete pump-down cycle from atmospheric to end pressure. In this case the vacuum meter is used as data logger which stores the measurements in the internal data memory. Via USB interface those data can then be transmitted to a PC for further analysis and documentation.
