Kymograph mounted on a trolley and powered by mains electricity, the trace would be recorded on smoked paper, unsigned, British, 1945-1950
The kymograph is a standard laboratory measuring device that can record a variety of phenomena. Its inventor, German physiologist Carl Ludwig (1816-1895), used it to record arterial blood pressure. Kymographs consist of a drum, which rotates at a steady speed. An arm holding a pen or stylus then moves in response to the phenomena. It records the results on the drum over a period of time. This kymograph is fixed to a trolley and is powered by mains electricity rather than batteries or clockwork.
