Manometers are pressure testing devices usually associated with pressures close to that of atmospheric pressures. Pressure can change quickly as the altitude changes, making manometers valuable tools in determining the differences. In a vacuum or in a slightly pressurized area manometers are used.

This model of manometer is designed to give differential pressure readings between two different pressurized components. This meter also comes with Windows compatible software which organizes, analyzes and graphs the pressure readings as they come in. This is great for tracking the pressure differentials.

The LCD screen features large letters and is backlit for use in all lighting conditions. This meter also features an AC adaptor for 100V-240V receptacles, so the pressure testing rarely has to stop.
