There are several advantages of using electronic manometers. An electronic manometer is portable and more compact than the old fluid-filled types. The UEi Test Instruments EM201B test dual input differential manometer is more accurate and provides a greater resolution than older versions, and a digital display is easier to read.

Static pressure is the measurement of all the resistance in the duct system that the fan has to work against such as filters, grills, A/C coils, and the ductwork. Measuring and understanding the static pressure in an HVAC system is important for an HVAC technician to get a general idea of the systems overall condition.
