<p class="p1"><b>What is Fixed-Point Temperature Calibration?</b></p>
<p class="p1">Fixed-point temperature calibration involves the use of materials that undergo phase changes at precisely defined temperatures. These materials, known as fixed-point cells, exhibit unique physical transformations, such as the solid-liquid transition of pure metals or the triple-point of certain substances. These fixed points occur at accurately known temperatures that can be reproduced with exceptional precision. By comparing the behavior of a temperature measuring device to a fixed-point cell, the instrument's accuracy can be determined and adjusted if necessary.</p>
