Barograph c.1880

This barograph dates to around 1880 and stands 17.75cm high with a base measuring 33.25cm × 18.5cm, and it comes with recording sheets. A barograph is a precision instrument used to continuously record changes in atmospheric pressure over time. Instead of giving a single reading like a standard barometer, it uses a system of aneroid capsules linked to a pen that traces pressure changes onto a rotating paper chart. Instruments like this were widely used by meteorologists, ships’ navigators, and scientific observers to monitor weather patterns and predict approaching storms. Its mechanical movement and continuous recording make it both a practical scientific instrument and a fascinating example of late 19th-century engineering.
