Tem­per­a­ture mea­sure­ment tech­nol­o­gy is a sub­field of phys­i­cal mea­sure­ment tech­nol­o­gy and a col­lec­tive term for pro­ce­dures, meth­ods and process­es for record­ing, con­trol­ling, mon­i­tor­ing, test­ing and de­ter­min­ing tem­per­a­tures. Tem­per­a­ture mea­sure­ment tech­nol­o­gy pro­vides in­for­ma­tion about the ther­mal state of sol­id, liq­uid and gaseous sub­stances. Its re­sults in­di­cate how hot, warm or cold an ob­ject, a sur­face, a medi­um, a flu­id or a sys­tem is. Tem­per­a­ture is mea­sured pri­mar­i­ly in de­grees Cel­sius (°C) or Kelvin (K). In ad­di­tion, there are oth­er tem­per­a­ture scales such as de­grees Fahren­heit (°F) or de­grees Reau­mur (°Ré). Tac­tile or non-con­tact ther­mosen­sors, ther­mo­cou­ples and re­sis­tance ther­mome­ters are used in in­dus­tri­al ap­pli­ca­tions as a means of tem­per­a­ture mea­sure­ment. Among oth­er things, tem­per­a­ture mea­sure­ment tech­nol­o­gy is in the ser­vice of process con­trol, op­er­a­tional safe­ty, qual­i­ty as­sur­ance and process control.
