History of ATCO Barometer

Barometers have been instrumental in meteorology for centuries, with the first mercury barometer invented by Evangelista Torricelli in 1643. Aneroid barometers, like this one, which use a sealed metal chamber, became popular in the 19th century due to their portability and robustness. German manufacturers, including ATCO, were renowned for producing high-quality weather instruments, which were widely used in homes and maritime settings for local weather forecasting.
