Ear thermometers are widely used in a clinical setting for the measurement of patient temperature, whereas forehead thermometers have been increasingly used during the pandemic as a method of fever screening. For reliable body temperature measurement, the performance of the devices needs to be validated by calibration using a suitable blackbody source. Fo...

**Calibration of Thermometers Avoiding the Use of Mercury** High-accuracy laboratory thermometers need to be calibrated by using 'fixed point cells'; cells are used to calibrate thermometers to the highest accuracy, and cells rely on the phase change of a pure substance. At higher temperatures, pure metal ingots are encased in an assembly into which a the...
