Einthoven galvanometer

This galvanometer can be found in the Charité, in Berlin. The string galvanometer, developed by the physiologist Willem Einthoven, served for the measurement of lowest electrical currents of the heart, the nerves as well as the brain. It belonged to the most important apparatus in electrophysiology and consists of a quartz string with string mounting, an electromagnet and a microscope for the observation of the string. The electrical current deflects the string depending on the amperage.1
