Temperature Measuring Products

Temperature measurement

Temperature measurement is the process of determining the degree of hotness or coldness of an object, substance, or environment. Temperature is typically measured in units such as degrees Celsius, Fahrenheit, and in research applications, Kelvin.

Methods Include

There are many methods and devices that can be used to measure temperature, depending on the specific application and the accuracy and speed required. Some common temperature measurement methods include:

  • Thermometers: These are devices that contain a temperature sensor, such as a liquid or gas, that expands or contracts with changes in temperature. The resulting change in volume is measured and converted into a temperature reading.
  • Thermocouples: As described in the previous question, these are devices that generate a voltage due to the thermoelectric effect when two different metals are joined together, and the voltage is converted into a temperature reading.
  • Infrared sensors: These sensors detect the amount of infrared radiation emitted by an object, which is related to its temperature. Infrared sensors are often used in non-contact temperature measurement applications, such as for measuring the temperature of a hot object without touching it.
  • Resistance temperature detectors (RTDs): These are devices that use a metal resistor, typically made of platinum, whose resistance changes with temperature. The change in resistance is measured and converted into a temperature reading.
  • Thermistors: These are temperature-sensitive resistors that change their resistance in response to changes in temperature. Thermistors are often used in applications that require high accuracy and precision.



Temperature measurement is important in many fields, including manufacturing, food processing, medical research, and climate science. Accurate temperature measurement is essential for maintaining quality control, ensuring safety, and understanding fundamental physical and chemical properties of materials and substances.
