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.
Comfort temperature
This function lies in the fact that the thermometer "evaluates" the surrounding conditions — how comfortable they are for a person — and displays the result on a scale. It can be implemented in different ways, depending on the purpose (see above).
So, in models for water, additional marks on the scale are used — “Cold”, “Hot”, “Optimal” (for bathing a child); it is much easier to assess the temperature of water on them than on a scale with degrees. In domestic electronic models (see "Type"), the comfort is often determined by a combination of temperature and humidity. And in models with the possibility of external measurements,
the comfort temperature can mean the perceived temperature. The meaning of this indicator is that at high humidity, both heat and cold are felt more acutely — as if it is hotter or colder outside than it really is. Some thermometers are able to estimate what temperature will correspond to the sensations of a person who went outside; This allows you to dress for the weather.
