Dual Scale Bottom Connection | Dual Scale, Center-Back Connection | Bottom Connection | Center Back Connection |
A glycerin-filled dial reduces needle flutter for precise readings in high-vibration applications. Also known as compound gauges, these measure both pressure and vacuum. Use them with pumps, filters, regulators, compressors, and in suction and process lines.

Absolute Pressure Gauges

Bottom Connection |
Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. They’re often used in laboratory applications, and they are barometrically independent.
Stainless Steel Case—Stainless steel gauges have excellent corrosion resistance, so they can be used with more corrosive liquids and gasses than gauges with a brass connection and aluminum case.
Torr—Gauges with a Torr scale are also known as Torr gauges.
