The versatile VD810 digital vacuum meter with data logger and USB interface measures absolute and relative pressure in the rough vacuum range with a resistant Piezo sensor.
Measurement principle: Piezo resistive
Gas dependency: independent of gas type (Piezo)
Measurement range mbar: Absolute Pressure: 2000 – 1 mbar, Relative Pressure: -1060 … +1200 mbar (depending on ambient pressure)
Logging rate: 20 ms … 60 s
