Pressure and Vacuum Gauges

Gauge Guards

Also known as isolators or diaphragm seals, these protect gauges from corrosive process media.

Sanitary Gauge Guards

Keeping corrosive substances from touching pressure gauges used in food-processing and pharmaceutical plants, these guards have a sanitary design.

High-Pressure Gauges for Chemicals

Use in high-pressure applications up to 2,000 psi.

Low-Pressure Gauges for Chemicals

Use in low-pressure applications up to 160 psi.

Vibration-Resistant Pressure Gauges for Chemicals

These gauges have a liquid-filled dial that reduces needle flutter in high-vibration applications reaching 2,000 psi.

Pressure Gauges

These are the most commonly used pressure gauges. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.

Pressure Testing

Ultra-High-Accuracy Digital Test Gauges for Pressure

With an accuracy of ±0.05%, these have the highest accuracy of all our test gauges.

High-Accuracy Digital Test Gauges for Pressure

Gauges have an accuracy of ±0.25%.

Test Gauges for Pressure

Test and calibrate transmitters, gauges, and other equipment that measures pressure.

Corrosion-Resistant Test Gauges for Pressure

All-stainless steel construction makes these gauges suitable for testing and calibrating in corrosive environments.

Vibration-Resistant Test Gauges for Pressure

These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications.

High-Accuracy Test Gauges for Pressure

With an accuracy of ±0.25%, these gauges are designed for critical processes that require precision.

Test Gauges for Vacuum

Use these gauges to test and calibrate transmitters, gauges, and other equipment that measures vacuum.
