The Einthoven string galvanometer is another form of sensitive instrument for the measurement of small direct currents.
The very elaborate and delicate electrocardiograph with the string galvanometer devised by Einthoven is used.
The Einthoven galvanometer consists of a very powerful electro-magnet, the pole pieces of which converge almost to points.
The valve receiver is connected to the battery B and silvered quartz thread K of an Einthoven galvanometer (already described).
The principle of the Einthoven string galvanometer may be described roughly in a few words.
Professor Korn uses a form of the Einthoven galvanometer already described.
