A manometer is used to measure the pressure of liquids or gases. PCE Instruments offers handheld digital manometer products as well as flanged manometer and fixed manometer products for use in a variety of practical pressure measuring applications.

A handheld digital manometer commonly is used to measure differential pressure in heating, ventilation and air conditioning (HVAC) systems. Differential pressure references the difference in pressure between two points. For example, an HVAC service professional might compare the difference in pressure in front of and behind an air filter when performing duct system diagnostics.
