    Abstract

    A hysteresigraph of high accuracy and sensitivity is described. Using galvanometer-photoelectric integrators, this instrument was the first precision recording fluxmeter for tracing accurately and rapidly magnetization curves and hysteresis loops directly on standard rectangular coordinate paper to any desired scale for direct reading of the data. Overall error of this hysteresigraph can be reduced to 0.2 percent by calibration of the overall system with a precision search coil of certified accuracy and a magnetic field accurately determined by means of a nuclear resonance magnetometer.
