Air temperatures
Possibility of using a thermometer to measure the air temperature. Usually, such a measurement is carried out by a separate sensor, due to which this function is found not only in contact, but also in IR thermometers (see "Type").
Liquid temperatures
The ability to measure
the temperature of liquids using a thermometer. The method of such measurement can be both contact and non-contact. One of the most popular uses for this feature is when preparing baby food.
Measurement range
The range of temperatures that a thermometer can measure.
For measuring body temperature, a range of 35 – 43 °C is considered ample, covering values encountered in individuals with high fever or hypothermia. Although modern medical thermometers may have broader ranges, especially those designed for water and air temperature measurement (e.g., -20 – 100 °C), when used for body temperature, they typically operate within a narrower range. The overall and "solid" measurement ranges are often specified separately in these thermometers.
Reading memory
The number of results the thermometer can store in memory. The ability to
"remember" the results of previous measurements can be very convenient in some cases — in particular, it allows you to accurately track changes in temperature over time. The most advanced models are capable of storing several dozen readings in memory.
