The Vacuum Research Diaphragm Manometers are compact vacuum measurement and control instruments that are unaffected by gas composition. The sensors have 316 L stainless steel diaphragms and any sensor can measure liquid or gas pressure as well as vacuum.

Response time is less than 400 milliseconds for full scale and sensors are available with a variety of flanges including VCR and KF or NW styles. With any sensor, these instruments offer the precision and high resolution of digital electronics at the same price as analog instruments. Both indicator and controllers are provided in 1/4 DIN enclosures.

The Dual Set Point Controller operates two control relays. Set point values are adjusted from the front panel and displayed on the meter. Push-to-set switches simplify display of the set point pressures. Relays have 3 Amp contacts, SPDT, and have screw terminal connectors on the rear of the instruments.
