What is the Difference between models 267 models and the 287 models ?


in principle the function of both Barograph version is the same, the measuring & recording of the absolute air pressure.
Nevertheless there a some differences between 267M and 287M which causes the significant price difference:

The 267M has another housing with 5 glasses (faceted float glass), the 287M housing has only 4 glasses (closed cover).
Besides of this the mechanics are different. All parts of the movement of the 267M are made of polished brass, the 287M
has a black movement holder (aluminum), the transmission is also made of polished brass.

Measuring

  • It uses a set of 7 aneroid capsules with a diameter of 62 mm made from copper-beryllium alloy. This material essentially eliminates age-hardening, hysteresis, and elastic after effects that could otherwise degrade the accuracy. 
  • The influence of temperature on the set of aneroid capsules and the transmission system is compensated by use of bi metal components over the full measuring range and for temperatures between -30 to +40 °C (-22 to 104 °F). 
  • All contacts in the movements are jeweled to reduce friction.
