MKS Baratron® capacitance manometers are highly accurate and repeatable, insensitive to gas composition, compact, and easily interfaced with most process tools. We manufacture our manometers almost exclusively using nickelbased alloys such as Inconel®, Incoloy® and others. This makes them highly resistant to corrosion when the materials are matched to the process. Our sensors are fully welded and 100% leak-checked prior to assembly. In the event of an extremely rare failure of the diaphragm, the process gases are completely contained within the sensor, preventing escape to the outside environment. No other pressure or vacuum gauge offers that level of safety.
