Glossary

Measurement range

Total allowable measurement range. The minimum / maximum temperature that the thermometer is able to fix, as a rule, is also acceptable for using the device — with further cooling / heating, malfunctions are possible up to complete failure.

Low values of this parameter are crucial for outdoor dryer models. Additionally, the inherent "margin of safety" in measuring systems often results in finding sub-zero temperatures in purely indoor models. This feature can be practical, such as assessing conditions in an unheated room during winter.

Most contemporary household thermometers boast a maximum temperature range of 50 — 60 °C, sufficient for even relatively hot climates. However, there are less heat-resistant models with temperatures ranging from 30 — 40 °C. Thermometers designed for water applications have a lower maximum temperature, as it is not necessary for their intended use. Sauna thermometers typically exhibit the highest temperature resistance.

Fixing min/max temperature

The possibility of "remembering" the maximum and minimum temperatures recorded for a certain period of time by the thermometer. Thanks to this, the user can determine the range of temperature fluctuations during this time, even if he was not nearby at all. Such an opportunity can be useful, for example, to assess the efficiency of heating a house in the absence of owners, to control climatic conditions in a warehouse, etc.
