While there are a few different types of barometers, Maximum specializes in aneroid barometers with the Proteus and Predictor models, as they are a safer way to measure atmospheric pressure than by using mercury and require no external power source, unlike digital barometers.

A barometer is a device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. There are two main types of barometers: mercury and aneroid. Learn more about barometers in this article.

Aneroid barometers. The aneroid barometer measured air pressure according to the movement of mechanical parts, rather than the expansion of a liquid, and it is capable of produced readings more accurately than spirit or mercury barometers.

Aneroid barometers offer a more portable and user-friendly alternative to mercury barometers. They use a flexible metal diaphragm that expands or contracts based on atmospheric pressure changes. This movement drives a mechanical linkage that indicates pressure on a calibrated dial.
