The integrating fluxmeter disclosed herein employs a second electronic integrator which operates during the intervals between test periods to adjust a compensating bias current, applied to the main integrator, to a value accurately canceling any residual drift. The integrating capacitor employed in this second electronic integrating circuit is of sufficient size so that the value of the compensating current does not vary significantly during a test period.
