A thermistor is a type of resistor whose resistance changes with temperature. Thermistors are used in a variety of applications, including temperature measurement, temperature compensation, and flow measurement. Checking a thermistor involves measuring its resistance and comparing it to the manufacturer’s specifications.
Thermistors are important because they allow for the precise measurement of temperature. They are also relatively inexpensive and easy to use. Thermistors have been used for over 100 years, and they continue to be an important part of many electronic devices.
