Dampened Deluxe Quartz Barograph

Keep precise records of barometric pressure readings with this extraordinary German-made Dampened Deluxe Quartz Barograph. This mechanical barograph with eight round diaphragms measures variation in the air pressure and transfers the information very precisely through a system of mechanical levers to the writing arm.  

The battery operated quartz movement rotates the solid brass drum once a week, requires no winding and is more accurate than key-wound movements. The conventional ink nib and messy ink bottle are replaced by a convenient felt tip pen which lasts 6 to 9 months.  This barograph model includes a bottle of oil damping fluid for the arm to avoid incorrect readings when on ships or yachts at sea. The elegant mahogany and glass case is polished to a high luster finish and is hinged for easy access to the movement for change of paper and pen.

  • Chart duration: 7 days
  • One-year supply of weekly charts (#108) included
  • AA battery
  • One felt tip pen (#451) included
  • Damping fluid (#110) included
  • Millibar charts (#107) available separately
