Wempe USA

$ 2,890.00

Drum barographs are essential for anyone who wants to keep an exact record of changes in air pressure. Wempe drum barographs are made of high-quality materials and are individually assembled by hand. Eight aneroid capsules are the centerpiece of each barograph. They measure the exact air pressure, which is recorded on the diagram paper by means of a precision mechanism and writing arm. The paper drum itself is battery-powered. 

All Wempe drum barographs come with 52 sheets of diagram paper for a full year and a felt-tip pen.
