About Pressure Gauges

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. 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.
