4.5kgsWho would use an Aneroid Barograph?
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.
