Measuring Barometric Pressure

barometer

Barometers are instruments that are used to measure Barometric Pressure (air). This device has been an integral part of the British domestic scene since the early part of the 18th Century. It's able to measure the weight of the column of air that extends from the instrument to the top of the atmosphere. Barometers are useful tools that help in weather forecasting, as changes in pressure are used … [Read more...]
