FIELD: measurement equipment.
SUBSTANCE: according to the invention, in order to determine hydrogen content in products made from titanium in layers as to depth of a specimen the value of eddy current is determined at different frequencies; with that, at each frequency there determined is maximum value of eddy current depending on angular position of a sensor; resistances R1 and R2 are measured on frequencies corresponding to difference of depths a1 and a2; electrical conductivity is calculated for the specified depth ax=a2-a1; then, as per calibration reference dependence of electrical conductivity on concentration of hydrogen in titanium there determined is the unknown hydrogen content in a layer as to depth of a titanium product (specimen).
EFFECT: invention provides the possibility of determining hydrogen content in layers of titanium saturated with hydrogen, which are located at different depth, and improves accuracy of determination of hydrogen content.
