287M Marine Barograph (mechanical clockwork)

"287M | Barograph for ships"

Aneroid barograph used for the registration of atmospheric pressure with damped measuring mechanism for use at see.

  • Measuring range 955 to 1055 hPa
  • Accuracy ± 0.7 hPa
  • Diagram graduation 1 hPa.

The measuring element in our barographs is a set of 7 aneroid capsules with a diameter of 62 mm. This set is manufactured of a copper-beryllium alloy which by its remarkable elastic composition has been tried and tested best for many years.Age-hardening, hysteresis and elastic after effects don`t occur practically. The influence of temperature on the set of aneroid capsules and the transmission system is compensated by a bimetal about the whole measuring range and for temperatures between -30 and +40°C (-22 ... 104 °F). All the axles of the precision instrument are supported in jewels because of this the instruments have only got a minimum of idle friction.

Parts of the measuring mechanism are made of polished brass.

Mahogany colored wooden case 345 x 170 x 180mm.
The barograph is equipped with mechanical winding up clockwork which can be shifted in an instant for daily or weekly revolution. The periods are 25.6 h / 176 h.
