AI Technical Summary
Technical Problem
Existing temperature measurement devices are easily affected by the sample holder and reflected radiation when measuring test samples with large differences, resulting in distorted measurement results.
Method used
A sample holder with an adjustable aperture is used, with the aperture positioned on both the front and back sides of the sample in the radiation direction to shield the interference parts of the sample holder and the radiation reflected from the sample, thus ensuring the accuracy of the light beam and radiation detection.
Benefits of technology
It effectively reduces the interference of sample holder and reflected radiation on measurement results, and improves the measurement accuracy of temperature conductivity, heat capacity and thermal conductivity.
