| Zusammenfassung: | The functional form of the Steinhart-Hart equation which describes the electrical characteristics of NTC thermistors, is studied particularly with regard to its metrological properties. This equation is almost exclusively used in the community and it is even hard-wired in many commercial instruments. However this equation (in its original form) does not follow the rules of quantity calculus and it is not unit invariant. Therefore the naive use is error prone. In this contribution proper metrological concepts to avoid pitfalls are presented. |
