About Pressure Gauges

Digital High-Accuracy Pressure Gauges

A digital display allows for easy reading of measurements.

Large-Dial High-Accuracy Pressure Gauges

Read your pressure from a distance with these large-dial gauges.

Vibration-Resistant Pressure Gauges

A liquid-filled dial reduces needle flutter for precise readings in high-vibration applications.

Low-Pressure Differential
Gauges with Digital Display

Gauges have a digital display for easy reading of measurements.

Pressure and Vacuum Transmitters

Pressure Transmitters with Digital Display

Read pressure directly at the source and send data remotely with one device.

Pressure Transmitters for Compressed Air

With a pressure range common to most compressed air systems, use these transmitters to monitor your system's air pressure.

Absolute Pressure Transmitters

Monitor and control pressure in portable HVAC systems, hydraulics, and oil and gas equipment. Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature.

Pressure and Vacuum
Transmitters with Digital Display

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display.

Pressure and Vacuum
Transmitters for Compressed Air

Specifically made for compressed air and gas systems, these transmitters remotely monitor pressure and vacuum.

Vacuum Transmitters for Compressed Air

Designed for compressed air and gas systems, these transmitters remotely monitor vacuum.

High-Accuracy Digital Test Gauges for Pressure

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%.

Vehicle Maintenance and Dock Equipment

Tire Inflator Gauges

Mate these gauges to a compressed air line to measure pressure while inflating tires.

Compression Testers

Check engine compression to maintain top performance.
