ELECTRICAL RESISTIVITY DETERMINATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC G01N27/14 

FIELD: electricity.

SUBSTANCE: determination method of electrical resistivity for melts wherein a melting pot with melt is suspended coaxially in a cylindrical electric oven at the lower end in the resilient wire head while the upper end of resilient wire is fixed in the fixation unit. At that, before melt testing, length of the resilient wire head is changed by blocking the upper end of resilient wire in regard to the fixation unit. The device intended for determination of electrical resistivity for melts comprises a melting pot with melt is suspended coaxially in a cylindrical electric oven at the lower end in the resilient wire head while the upper end of resilient wire is fixed in the fixation unit. At that a clamp and a pin are introduced to it additionally; the pin is fixed non-coaxially in the fixation unit, the clamp is fixed at the pin, it may be moved along the pin and has the facility for fixation in the clamp of the resilient wire upper end.

EFFECT: reducing time for experiments and their simplification during determination of electric resistivity for different melts in case of their change.
