The aneroid barometer mechanism has eight stacked vacuum capsules and utilises a gate suspension, with a secondary barometer dial and an unusual inset thermometer. The barograph has a glass ink bottle recessed into the case.DimensionsHeight 9 InchesWidth 15 InchesDepth 9 InchesDelivery Information At Shackladys Antiques, we want your experience to be as enjoyable and as easy as possible.
