    • Stereometric barometer (Inv. 1137)

Stereometric barometer mounted on a shaped base with three leveling screws, similar to the device invented by Marsilio Landriani. The instrument basically consists of a barometric tube inserted in a brass container. The latter is fitted with a large glass tap and surmounted by an ivory cistern. A screw piston adjusts the mercury level. The barometric scale, in Paris inches, is engraved on a brass tube enclosing the glass barometric tube. The readings are taken by means of a rack vernier. The instrument can also be used as a normal barometer.
