AXD Micro-manometers measure differential and static air pressure, velocity, and volume in industrial applications including pressure gauge verification, velocity traverses in ducts, and filter performance checks, the company says. They measure pressure, calculate velocity, and calculate averages of pressure or velocity readings. According to the manufacturer, the top-of-the-line model calculates volume automatically when duct size and shape are entered, and stores up to five different K factors for use when measuring volume. It stores up to 1,000 samples of pressure, velocity, or volume; and calculates statistics for the stored samples. All stored data can be viewed on the instrument display or downloaded to a computer spreadsheet using the supplied downloading software, the company states.
