Abstract :
A new form of vacuum tube voltmeter that has certain merits not possessed by existing instruments is described by this paper. Advantage is taken of the properties of a bridge circuit, one of whose arms is the plate-filament impedance of a common three-element pliotron to permit the building of very sturdy instruments of unusual sensitivity and dependability.
