WebThe IR thermometer works by focusing light that is coming from the object in the form of IR rays and funneling that light into a detector - which is also known as a thermopile. It is in the thermopile that the IR radiation is turned into heatÂ which is then turnedÂ toÂ electricity, which is then measured. WebA thermometer is calibrated by using two objects of known temperatures. The typical process involves using the freezing point and the boiling point of pure water. Water is known to freeze at 0°C and to boil at 100°C at an atmospheric pressure of 1 atm.

How To Use A Thermometer To Take Your Temperature

WebElectronic thermometers (RTD's, thermistors and thermocouples) measure the affects of heat on electronic currents. Resistance devices (RTD's and thermistors) take advantage of the fact that electrical resistance reacts to changes in temperature along predictable curves.
