The small dial on these gauges allows for installation in tight spaces.

Measure small pressure changes in ventilation systems, hydraulic applications, and other critical processes.

Keep tabs on liquid levels in pump and tank applications with these gauges—a dual scale displays pressure in feet of H₂O and psi.

Unlike other gauges that have multiple moving parts that can shake loose, these have only one internal part. They are the most shock-resistant gauges we offer.

Gauges have an accuracy of ± 2%.

Designed for use with boilers, these gauges measure pressure and temperature simultaneously.

Use in low-pressure applications up to 160 psi.

Use these gauges to monitor the pressure of compressed gas.

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

A 304 stainless steel case coupled with 316 stainless steel connection threads provide protection from corrosive environments.

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

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

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

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

Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure.
