Barometer Transit Plug

This barometer transport plug is designed to safely secure the mercury column when a mercury barometer is being moved or stored. Made from a sturdy metal rod with a fitted cork tip, it seals the mercury column to prevent movement, leakage, and damage to the glass tube during transport.

An essential accessory for antique, marine, and scientific mercury barometers, the plug should be disengaged before use to ensure accurate readings.
