The model 276 produces reliable consistent accuracy from 1 milliTorr through 760 Torr (atmospheric pressure.) The 276 leverages dual-sensor technology that offers the unique ability to accurately measure through the entire rough vacuum range of 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 physically equivalent to the Model 200; however, it adds high accuracy in the Torr ranges. The 276 adds accuracy approaching a capacitance manometer in the range of 10 Torr to 760 Torr/Atmosphere. This unit is also available with the ability to log onto a web page, Ethernet connectivity, RS232 communications, PC software that displays, plots and logs, and an analog recorder out. The 276 is also less sensitive to the composition of gasses, since it uses piezoelectric transducer technology in the 3-760 Torr range.
