Resumen
FIELD: measuring equipment.
SUBSTANCE: invention relates to the analysis of materials by photometric determination of the specific electrical resistivity of a heated body depending on the temperature, in particular to the determination of the specific electrical resistivity of metals and alloys in the liquid state. The device comprises a computer, a light source, a mirror disposed on a twisting elastic thread, on which a firepot with a charge is suspended, a photodetector, which is characterized in the fact that it is made in the form of at least one image sensor.
EFFECT: increased accuracy of measuring deviation angles ϕ of reflected light beam during temperature changes.
