No. 58c Robitzsch Type Radiation Recorder - Actinograph
*Beschreibung derzeit nur in englisch verfügbar

The Robitzsch Type Radiation Recorder measures the total of direct solar and diffuse celestial radiation reduced to a horizontal plane. The measuring accuracy of about ± 5 % is sufficient for all fields of application. Attendance of the recorder is easy for untrained persons, too.
58c - radiation recorder
The measuring system consists of three symmetrically arranged bimetallic strips, a black one in the middle between two whitened strips. Due to differential absorbtion a temperature difference is created between the strips which serves as a measure of radiation intensity. The position of the recording pen depends only on the temperature difference of the strips and is not influenced by the actual temperature level.

The sensitivity range comprises the entire spectrum of solar an celestrial radiation; only the longwave range > 2 μ is not included, this, however, contributes only very little to the total energy. The total radiation during measuring time in cal-2 is obtained by integrating the radiation curve. The radiation recorder in its present form has been considarably improved as compared with former models. These improvements are:

a) Greater measuring accuracy and independence of disturbing effects by the elimination of scattered radiation
   (Protective cap after Götz and Casparis).
b) Direct recording of radiation intensity in cal cm-2 min-1.
c) Device for conveniently applying time marks.
d) Set-to-zero without affecting the adjustment of the instrument.
e) Reduction of bearing friction by build in virbator.
