Not sure about an insuement, but an instrument for measuring air pressure is a barometer.
Air pressure
An air pressure measuring device is called a Barometer.
An advantage of using a barometer is that you can measure air pressure.
Because the pressure can be measured with a barometer.
decreasing
As air becomes cooler, it becomes more dense. As the air become more dense (heavy), it causes the barometer to rise.
increasing
A barometer does not measure temperature it measures pressure.
otherwise know as a barometer and it measures air pressure in newtons
A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.
When you increase air pressure the mercury in a barometer will rise. Conversely when air pressure decreases the mercury in a barometer will drop.
Air pressure is measured with a barometer.
