Atmospheric pressure describes the force exerted on a surface by the air. This can vary depending on a number of factors, including the altitude, temperature and composition of gases that make up the air. It is an essential parameter for forecasters, as it enables early detection of weather changes.
Knowledge of atmospheric pressure is also useful in a number of other contexts: e.g. when working at altitude, underground or in specially controlled environments, and for understanding the behaviour of air pollution.
Munro Instruments provides a comprehensive range of sensors to enable the measurement of barometric pressure.
