These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications. Use them to test and calibrate pressure gauges and other equipment. Gauges have a safety case that blows out in the back under excess pressure, protecting the operator in front.

Gauges with stainless steel guard provide protection from corrosive media.

Gauges with polypropylene case can handle higher temperatures than gauges with phenolic case.
