About Pressure Gauges

Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

Vibration- and Corrosion-Resistant Vacuum Gauges

Designed for harsh environments prone to vibration, these gauges pair a corrosion-resistant 304 stainless steel case with a glycerin-filled dial to reduce needle flutter. Use them with vacuum pumps, packaging equipment, and in suction lines to measure and display vacuum.

Vibration-Resistant Pressure and Vacuum Gauges


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.
