A study has been made of an external bridge thermogradientograph device which measures and records temperature value differences on the boundaries of a layer. Line diagrams, calculated correlations, dependence of instrument reading on layer temperature and slide-wire resistance, circuit sensitivity and selection of the diagonals for connecting the balancing device were some of the topics presented. A general formula for the true value of temperature difference, the effect of switching connecting lines into the external bridge, tolerances in manufacture, and total error of the instrument were also discussed.
