MKS® 722B Baratron® General Purpose Absolute Capacitance Manometer
(1 to 1000 Torr) Direct, Absolute, Analog Pressure/Vacuum Measurement - Ambient Temperature Operation
The 722B Baratron General Purpose Absolute Capacitance Manometer is a compact, low-cost manometer for accurate, repeatable, and reliable measurement. Robust sensor construction allows high overpressure tolerances, reducing errors caused by line pressure spikes.
- Small footprint reduces system size
- Overpressure limit assures no degradation in zero repeatability or performance
- All-metal, all-welded construction exposing only Inconel® and stainless steel for high corrosion resistance
- "Drop-in" replacement for several earlier Baratron manometers
The flexible, space-saving design of the 722B makes it the ideal solution for retrofit applications as well as new equipment designs.
