Product Description

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

The 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 instrument 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 in the Torr ranges and provides an alternative to a capacitance manometer in the range of 10 Torr to 760 Torr/Atmosphere.

This unit is also 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.

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.

Model 276 Dual Sensor Vacuum Gauge Accuracy:

0 to .009 Torr +/- 1 milliTorr

0.010 to 0.099 Torr +/- 7% of reading

0.100 to 2.5 Torr +/- 10% of reading

2.5 to 20 Torr + /- .5 Torr

21 to 400 Torr +/- 2.0 Torr

401 to 760 Torr +/- 1 Torr

    It’s still working perfect from 5-10 microns thru atmosphere. This really helped our chamber design. Thanks again.

  2. 5 out of 5


    We are very pleased with the units performance. We use the gauge to monitor lab scale medium vacuum and moderate vacuum distillations.

  3. 5 out of 5


    The 276 works great thus far. We have used it on a rotary evaporator as well as to check a freeze drier pump and done great!
