1. Development of a loop galvanometer, which was begun in the spring of .
1953 in the Construction and Experimental Department (Konstruktions-und
Versuchsabteilung)(KoV) of VEB Carl Zeiss, Jena, was successfully
completed in August 1953. Two models .are finished. The in was
developed on the basis of preparatory research carried out by former
Zeiss scientist rschau (fnu), who died in 1945. Froduction of the
device will begin in 1954.
2. The device consists of a container for the optics and a magnet case
which can be revolved around a horizontal axis. The magnet case con-
tains the loop holders which can be replaced, and two permanent mag-
nets, The following are the technical data en the device:
Interior resistance - about 7,5 ohms
Sensitivity
- from two times ten power minus seven to five
times ten power minus seven amperes per scale
part (A/Skt). The highest sensitivity is ob-
tained when the loop is in a vertical position.
3. Because of its small interior resistance and great sensitivity, the de-
vice can measure very weak thermecurrents,
