УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ ЛОКАЛЬНОЙ ТЕМПЕРАТУРЫ ПЛАВЛЕНИЯ

摘要

FIELD: thermal physics. ^ SUBSTANCE: device has heater, movable heat-conductive rod, set of contacts one of which is connected with rod and the other one is able to move along axis of rod. Device also has temperature pick-up and registrar. Working end of rod sharpened in shape of a cone. Rod is connected with case of heater by spring which allows to regulate force. Temperature pick-up is attached to sharpened end of rod. Heat-insulating cup is located between heater and surface of sample. Melting point can be measured without preparing samples in case when inclination or curvature of surface is presented. ^ EFFECT: reduced labor input. ^ 1 dwg
