An air pressure measuring device is called a Barometer.
Not sure about an insuement, but an instrument for measuring air pressure is a barometer.
Because Pressure gauge measures the the differenceof pressure so it is called pressure gauge not meter.

To measure the local pressure of the Earth's atmosphere, Torricelli invented the first Mercury Barometer.

Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges.
An easily portable instrument used for measuring air pressure is called anedroid barometer.
It's usually just called a "pressure gauge", the assumption being that you know, or a label on it tells you, that it is measuring water-pressure.
A Chinese scientist named Chang Heng invented a machine called Dragon Jar that was used to measure earthquakes.
