EMISSION AND CONDUCTIVITY

Suggesting approach to the problem allows to obtain three physical characteristics of substance using the device, i.e. change of conductive current, electromagnetic emission and vacuum changing due to gas release from the specimen or to measure thermoelectric current, electromagnetic emission and vacuum change; this fact increases accuracy of temperature measurements during phase transmission in glasses. There are two heating elements in the vacuum measuring cell, i.e. inner molybdenum furnace of 2.5 kW power and external removable Ni-Cr furnace of 3.5 kW power that allows to heat the specimen in the cell fast over wide velocity range from any small you like till 60°C per minute and to carry out heating from room temperature up to 1100°C.
