Voltmeter was used by the National Research Council in Applied Physics for Instrumental Optics.

Function

An instrument used to measure, in volts, the differences of potential between different points of an electrical circuit.

Horizontal reading, magnetically shielded, permanent magnet moveable coil type voltmeter. The light needle and low range makes this voltmeter ideal for measuring low voltage systems. It is also eminently portable. Mirror scale with knife-edge pointer to prevent parallax. Type-written chart glued to back indicates systematic error. Model popular in schools and universities. Except for the range, it is identical to 1977.0026.
