It features a user-friendly interface, powered by a replaceable 9V alkaline battery, and offers versatile barbed connections for easy integration with standard tubing. ## Description 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.

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 amount of pressure in a system relative to the ambient pressure, absolute pressure is the amount of pressure in a system relative to an absolute vacuum, and differential pressure is the difference between two pressures. Analog manometers are composed of columns of liquid, and they use gravity and the liquid's density to calculate pressure. Because they have no moving parts, analog manometers do not require re-calibration. Digital manometers have pressure sensors that are connected to a system with a hose to provide a digital readout of the amount of pressure present in a system. They use microprocessors to calculate pressure, and they require periodic calibration to help ensure accuracy.Dwyer Instruments manufactures measurement and control instruments, including pressure gauges, flow meters, level instrumentation, temperature instrumentation, and air quality monitors. The company, founded in 1931, is headquartered in Michigan City, IN. Review: Very happy with this - Very happy with this. Shipping was fast and I was able to set my gas pressures with no problems.
