Micro Fluid filled portable and stationary Manometers are indicators for the difference between two pressures & can also be used for single pressure. The inexpensive manometers measure positive, negative and differential pressures. Applications vary for the different types of stationary manometers. Manometers are unique in being both pressure measurement instruments and standards for calibration of other instruments.
Pressure is defined as a force per unit area and the most accurate way to measure low air pressure is to balance a column of liquid known weight against it and measure the height of the liquid column so balanced. The unit of measure commonly used are mm Hg / inches Hg using mercury as the fluid and mmWc / inches Wc using water or oil as the fluid.
