The application of an improved resistance-wire strain gage [3] to a multiple-unit instrument for the measurement of stress relaxation in single fibers is described. Forces are autographically recorded with a precision and accuracy of better than 3 mg. or 1/2% of full scale. The instrument is stable over long periods and is designed to record directly in units of stress, the scale being identical for all fibers.
