(Ästhesiometer nach Ebbinghaus. Gleicher Konstruktion wie das Doppel-Ästhesiometer nach von Frey, besitz dasselbe an Stelle der Borsten zwei Druckspitzen aus Elfenbein, welche durch feine Spiralfedern in Spannung gehalten werden.) 1903
taken from: Zimmermann, E. 1903. XVIII. Preis-Liste über psychologische und physiologische Apparate. (p. 0115, fig. 402)

Apparatus for examinations into perception, association and memory according to Ranschburg (mnemometer). The apparatus permits even without complicated time measuring apparatuses exact tests of the mesurement of the perception abilities of syllables, colors, numbers, optical stimulations etc. Moreover it enables simple and exact memory tests according to Ebbinghaus, Müller and Pilzecker and memory examinations according to Ranschburg with the determination of the capacity, security and duration of the reproduction of the memory. The in 60 fields devided stimulating card is visible in the diaphragm D and is moved in jumps by an electric magnet. The duration of the presentation varies by a metronome and a switch between 1/4 to 3 seconds. The stimulation can be continued optionally by pressing the button and it can be counted by the pendulum strokes. Connected to the chronoscope circuit the mnemometer serves also for the determination of the duration of reproduction as well as an optical apparatus with automatic presentation of the stimulations for every kind of time measurement tests. A more detailed description in: Mtsft. f. Pschatrie und Neurologie, vol. X, issue 5: Complete with spring interruptor, metronome, button and conduit: 3,600 kg.
