Vintage Maxant Industries Barograph For Sale

This vintage Maxant Industries barograph is a meteorological instrument designed to continuously measure and record atmospheric pressure. It is housed in an elegant dark wood case featuring clear glass viewing panels and a sturdy brass carrying handle. Inside, a brass aneroid mechanism expands and contracts with air pressure changes, moving a mechanical arm equipped with a pen to trace a continuous line on the paper chart. The paper chart is mounted on a rotating cylindrical drum that tracks the pressure across the days of the week. A label on the underside identifies the manufacturer as Maxant Industries (REF 40020) and specifies that it uses a \"WEEKLY CHART 239.2.S\".
