The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with Mercury that it turned upside down into another container filled with mercury.

Atmospheric air pressure is measured with a barometer. A manometer is a pressure guage used to to measure comparative pressures of any gases.

There are several options depending on the type of air pressure being measured:In the 1800's ships used a weather glass - a simple barometer - to measure changes in air pressure.To measure atmospheric (ambient air) pressure, a barometer is used. (It may be either an aneroid or a Mercury type of barometer.)For tires, it's a tire pressure gauge.In industrial processes and boilers the gauge is frequently called a manometer.For pressure vessels it is a Bourdon gauge.
I think you mean forceps. If you do, it is a handheld instrument used to grsp things. It is usually called this in medicine.

A manometer is an instrument that can be used to measure the pressure in an enclosed container that is filled with gas. The manometer is sometimes called a pressure gauge.

An easily portable instrument used for measuring air pressure is called anedroid barometer.

An instrument that is used by people to determine how hot or cold they are is called a thermomenter. A person may need to check their temperature if they feel they are running a fever.
