The Dual Sensor Vacuum Gauge (DigiVac Model 276) produces reliable, consistent accuracy from 1 milliTorr through 760 Torr (atmospheric pressure).

The Model 276 leverages dual sensor technology that has the unique ability to accurately measure through the entire rough vacuum range from 1 milliTorr through 760 Torr.

This dual sensor vacuum gauge builds on the simplicity and success of our best selling vacuum gauge –the Model 200. We do this through a seamless combination of sensing technologies integrated into a single easy to use bench top unit.

The Model 276 is the same size as the Model 200; however, the Model 276 adds high accuracy across the full range. Provides an alternative to a capacitance manometer in the range of 10 Torr to 760 Torr/Atmosphere.

This unit is option rich with the ability to be made available with the ability to log to a web page, Ethernet connectivity, RS232 communications, PC software that displays, plots and logs, and an analog recorder out. Contact technical support to quote these additional options. You can easily make this a wide range vacuum process controller with the addition of relay set-points (2C)

Importantly, compared to a capacitance manometer The Model 276 is less sensitive to the composition of gasses since it uses piezoelectric transducer technology in the Torr range.

Delivered pre-calibrated with sensor under actual vacuum against the NIST standard. Note: NIST certification sent with the gauge is an available option here
