Tech Tips: Differential Pressure Manometers
What is a Differential Pressure Meter?
A Differential Pressure Manometer can measure and display gauge, vacuum, or differential pressure (the difference between two pressure signals).
Pressure and Vacuum
In industry there are processes that push or press (pressure) and those that pull (vacuum). Pipes, hoses, pumps, and cylinders are filled or emptied of such materials as water, oil (hydraulics), air (pneumatics), and gases in order to perform various tasks.
What are the units of measure for pressure and vacuum?
Units of measure include: Pounds per Square Inch (psi) and inches of water which are common in the U.S. and Millimeters of Mercury (mm Hg), a popular metric unit. BARS and Atmospheres units are also supported and are for specialty uses. The Extech
HD700 offers eleven (11) units of measure.
The Extech HD700 Differential Pressure Manometer
The HD700 is a heavy duty, portable, digital Differential Pressure Manometer. This device measures pressure in the range of ±2.000 psi. The HD700 offers eleven (11) units of measure (user selectable by front panel pushbutton) and has a differential input that uses convenient quick-disconnect fittings. Advanced features include DATA HOLD, MIN-MAX-AVG RECORD mode, ZERO/OFFSET, AUTO POWER OFF, and USB PC interface.
