FIELD: measurement equipment.
SUBSTANCE: flat tested sample of available thickness is placed between two diamond anvils with heat conductivity, considerably exceeding heat conductivity of the sample, and exposed to high pressure, having previously installed a heater into the upper anvil. Also the value of external pressure impact is changed. By the change of temperature difference between upper and lower anvils they calculate relative change of sample heat conductivity during pressure variation. The heat source capacity is at the same time permanent.
EFFECT: increased accuracy of produced data.
