Absolute Pressure Gauges


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.
Gauges with a Torr scale are also known as Torr gauges.
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.

Differential Pressure and Vacuum Gauges with Digital Display
Gauges have a four-digit LCD display for easy reading of measurements. Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements. They are also known as compound gauges.

- For Use With: Air
- Accuracy: ±0.5% Full Scale (Not Graded)
