AN ORIGINAL WORKING STANDARD OF THE UNIT OF MAGNETIC INDUCTION GRADIENT

摘要

An original operating standard of the unit of magnetic induction gradient, developed at the Mendeleev Institute of Metrology, is described which enables one to calibrate working standards, intended, in turn, for calibrating industrial magnetic gradiometers. The total expanded uncertainty (k = 2) of the reproduction of the unit is 0.3% in the 0.01-10 mT/m range.
