Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.
Service these gauges without removing them using air filter kits. Kits include two vent valves for releasing air.
Surface mounting brackets allow gauges to be quickly installed on any flat surface. L mounting brackets can be carried to wherever you need to take a pressure reading. They can stand alone or be hung. Wraparound mounting brackets make it easy to service tubing, and don’t require cutting a hole in the wall.

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. They are commonly used to indicate clogged filters.
Magnet-mount gauges can be moved for use in multiple locations. Gauges with barbed tube connection have a flexible body that rolls up for storage or transport.

Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment. Install them in duct through a hole and connect to your gauge with tubing.
Sensors with pressure tubes give more accurate measurements in applications with high air flow. Style D is held in place with a magnet so you can move it for use in multiple locations.
