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

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

Easier to read than U-tube gauges, these use an inclined scale to measure pressure or velocity changes in air applications. They are also known as manometers.

Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements.

View readings at the source with the dial indicator or remotely using a receiver—these transmitters measure the difference in pressure between two inputs in liquid applications.

Check the difference in air pressure between two inputs at the source using the dial indicator or remotely using a receiver.

Remotely monitor the difference in air pressure between two inputs with these transmitters.

Safe for use in environments where flammable gases and vapors are present, these transmitters measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. They meet NEC safety standards for protection against an explosion.
