Compact vacuum meters with data logger
Compact vacuum meter: Piezo resistive, independent of gas type (1200 - 1 Torr)
The VD81 has a chemically resistant ceramic sensor. Like all other VD8 compact vacuum meter, the VD81 has a integrated data logger and an USB interface.
Compact vacuum meter: Heat conduction Pirani, dependent of gas tpye (75 - 5e-4 Torr)
The VD83 has a durable Pirani sensor with an elastic helix filament. Like all other VD8 compact vacuum meter, the VD83 has a integrated data logger and an USB interface.
Compact vacuum meter: Heat conduction Pirani, dependent of gas type (75 - 1e-3 Torr)
The VD84 vacuum meter has a external Pirani sensor with durable, elastic helix filament. Like all other VD8 compact vacuum meter, the VD84 has a integrated data logger and an USB interface.
Compact vacuum meter: Piezoresistive / heat conduction Pirani (900 - 5e-4 Torr)
The VD85 vacuum meter measures with a combination sensor piezo/Pirani. The heat conduction Pirani has a durable, elastic helix filament. Like all other VD8 compact vacuum meter, the VD85 has a integrated data logger and an USB interface.
