electrometers

At exactly the moment we added bromine, the conductivity jumped so rapidly that he couldn't switch the range of the electrometers.

Hideki Shirakawa - Autobiography 2001

To assist in his experiments he constructed several delicate pieces of apparatus - balances, electrometers, piezoelectric crystals, etc.

Pierre Curie - Biography 1967

The revolution in technique has come about not from any increase in the sensitivity of galvanometers and electrometers but from the use of the thermionic valve to amplify potential changes.

Edgar Adrian - Nobel Lecture 1965

The jars of Lord Kelvin's electrometers, which insulate very well, are made of white flint glass manufactured in Glasgow, but it is found that occasionally a particular jar has to be rejected on account of its refusing to insulate, and this, if I understand aright, even when it exhibits no visible defects.

The two electrometers were connected together by means of a conductor

Coulomb's torsion balance has been adapted by M. Baille to the measurement of low electromotive forces in a very successful manner, and has been found preferable by him to the delicate electrometers of Sir W. Thomson.

It is based upon the simultaneous working of two pith-ball electrometers, combined with the synchronous running of two clock-work movements.

The call effected, the first operator continued to revolve the machine so that the balls of pith should diverge in the two electrometers.

On a shelf set in the bulkhead was a chart, a telephone receiver, speaking tubes, dials with red and black hands, an array of electrometers, pressure gauges.

Then I saw littered about his feet the shattered remains of the best of our electrometers.
