Another early pioneer was Lippmann capillary electrometer fixed to a projector.
2.
Berger connected these sensors to a Lippmann capillary electrometer, with disappointing results.
3.
After a few months, Waller successfully recorded the first human electrocardiography using the capillary electrometer.
4.
In 1884 he became a lecturer in physiology at capillary electrometer to record the first human electrocardiogram.
5.
This field highly benefitted from the technical developments occurring in the capillary electrometer in order to use it for measuring subtle bioelectrical phenomena.
6.
The breakthrough came when Einthoven, working in Leiden, used his more sensitive string galvanometer, than the " capillary electrometer " that Waller used.
7.
Another method of making the test was by connecting the electrodes of a capillary electrometer to the two poles of a Daniell cell with a sulphate of cadmium solution.
8.
This device was much more sensitive than both the capillary electrometer Waller used and the string galvanometer that had been invented separately in 1897 by the French engineer Cl�ment Ader.
9.
Another method of making the test was, by connecting the electrodes of a capillary electrometer to the two poles of a Daniell cell with a sulphate of cadmium solution.
10.
Previous to the string galvanometer, scientists used a machine called the capillary electrometer to measure the heart's electrical activity, but this device was unable to produce results at a diagnostic level.
