The Dwyer Series 476A single-pressure digital manometer is used to perform single-pressure measurements and to set supply pressures, verify pressure switch operation, adjust regulators, check pneumatic systems, and computer peripherals. The meter is suitable for use with air and compatible gases, and has an accuracy of + or - 1.5% of full scale. The extruded aluminum case provides durability. The four-digit LCD displays the pressure measurement, and a zero function nulls minor pressure differences before measuring.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Manometers measure the pressure of a liquid or gas. They are used in laboratory, medical equipment, engineering, automotive, and heating, ventilation, and air-conditioning applications. Manometers measure any combination of gauge, absolute, or differential pressures. Gauge pressure is the
