The atmospheric pressure at any place is measured by _____?

1. Altimeter
2. Pressure Meter
3. Thermometer
4. Barometer

A barometer is a scientific instrument specifically used to measure atmospheric pressure. The most common types are mercury barometers and aneroid barometers. Altimeters measure altitude, thermometers measure temperature, and while a “pressure meter” is a general term, “barometer” is the precise name for the instrument measuring air pressure.
