Vibration-Resistant Drinking Water Pressure Gauges

Clearly read pressure levels in your drinking water system, even with heavy vibration. The dial face is filled with glycerin, which absorbs shock and keeps the needle steady.

Gas Pressure Gauges

Use these gauges to monitor the pressure of compressed gas.

Fire-Sprinkler Pressure Gauges

Gauges are UL 393 listed for use with fire-protection service equipment.

Pressure and Vacuum Gauges

Absolute Pressure and Vacuum Gauges

Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. They are also known as Torr gauges.

Refrigeration Pressure and Vacuum Gauges

Often used with chillers and in refrigeration systems, these gauges display the temperature of ammonia relative to the pressure measurement.

Vibration-Resistant Pressure and Vacuum Gauges

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

Solar-Powered Digital Pressure and Vacuum Gauges

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. Gauges have a digital display for easy reading of measurements.

Vacuum Gauges

Use these gauges with vacuum pumps, packaging equipment, and in suction lines to measure and display vacuum.

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.

Ultra-Low Vacuum Gauges

Accommodate applications with a vacuum range of -100 in. of H₂O to 0 in. of H₂O.

Corrosion-Resistant Vacuum Gauges

The case and connection threads are stainless steel for protection in corrosive environments.

Vibration-Resistant Vacuum Gauges

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

Differential Pressure Gauges

Low-Pressure Differential Gauges with Color Indicator

A band of green, yellow, and red provides a clear indication of changes in differential pressure.

Low-Pressure Differential Gauges with U-Tube

Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure.

High-Pressure Differential Gauges

Use in high-pressure applications up to 3,000 psi.

Medium-Pressure Differential Gauges

Use in medium-pressure applications up to 1,500 psi.

Gauge Protectors
