Vacuum Meter+Logger,Piezo/Pirani,Abs 1200 to 5e-5/Rel -1060 to +340 mbar
The digital VD850 vacuum meter
with Piezo/Pirani combination sensor,
data logger and USB interface reads pressure.
Measurement principle:Piezo resistive / Heat conduction Pirani
Gas dependency:Depending on gas type (Pirani),
independent of gas type (Piezo)
Measurement range:
Absolute Pressure: 1200 – 5.0e-5 mbar,
Relative Pressure: -1060 … +340 mbar
max. overload: 10 bar abs.
Resolution:
1200 … 1000 mbar: 1 mbar
1000 … 2.0 mbar: 0.1 mbar
2.0 … 1.0e-2 mbar: 3 digit
1,0e-2 … 1.0e-4 mbar: 2 digit
1.0e-4 … 5e-5 mbar: 1 digit
Logging rate: 20 ms … 60 s
