伊尔梅瑙理工大学开发了一种新的三重固定点黑体，在一个设备中包含固定点材料铝（凝固点660.323°C），锌（FP 419.527°C）和锡（FP 231.928°C）。只需对校准对象进行一次调整后，即可在三个固定点直接参考ITS-90来校准辐射温度计。该设置大大减少了校准过程的技术工作量和时间。本文介绍了用德国斯图加特的线性高温计LP-5测量相变温度和黑体温度随时间的变化。
A new triple-fixed-point blackbody containing the fixed-point materials aluminum (freezing point 660.323°C), zinc (FP 419.527°C), and tin (FP 231.928°C) in one device has been developed at the Ilmenau University of Technology. It enables calibration of a radiation thermometer with direct reference to the ITS-90 at three fixed points after a single adjustment of the calibration object. The setup significantly reduces the technical effort and the time for the calibration procedure. Measurements of the phase-transition temperature and the time-dependent blackbody temperature made with a transfer radiation thermometer, the Linearpyrometer LP5 of the IKE Stuttgart, are presented in the article.
