A fully electric radiosonde using the Finnish principle is described. The temperature is measured with a temperature sensitive dielectric; the humidity by the determination of the psychrometric difference; and the pressure by a corrugated diaphragm which positions a cylindrical condenser. The measuring elements and the construction of the sonde, as well as the calibration and receiving station, are outlined. The more important phases of the investigation are briefly mentioned, and a comparison of the temperature measurement with a number of other sondes is given.

* Short extract of a work done in the German “Marine Observatorium” at Greifswald during the years 1942 to 1944 under the Superintendent of the Instrument Department, Prof. Dr. Ing. R. Schulze. We gratefully acknowledge his helpful thoughts and support.
