Classic Barograph

Record barometric pressure with this mechanical German-made Classic Barograph that measures variation in the air pressure and transfers the data through a system of mechanical levers to the writing arm. Housed in a rich mahogany case with glass sides and a polished brass handle, this barograph equipped with a battery operated quartz movement with 4 diaphragms that rotates the solid brass drum once a week, requires no winding and is more accurate than key wound movements.

The barograph readings are marked on paper inch charts with a felt tip pen.

  • Chart duration: 7 days
  • One-year supply of weekly inch charts (#121) included
  • AA battery included
  • One felt tip pen, #451, (last 6-9 months) included
  • Millibar charts (#120-CH) available separately
