VD85 – Digital Compact Vacuum Meters / Data Loggers

Absolute Pressure 1200 – 5 x 10-4 mbar (=hPa), 900 – 5 x 10-4 Torr VD85 digital vacuum meter 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. It is equipped with USB interface and can be used as data logger (save up to 2000 measurements). The VD85 can be operated with battery or external power supply making it ideal for either portable or stationary applications.
