The types and measurement methods of thermometers may vary depending on the brand and model. Therefore, before use, it is necessary to carefully read the instruction manual and follow the instructions in the manual for operation. If you have any questions or discomfort, please consult a doctor or professional for advice in a timely manner.

According to the type of thermometer, read the displayed body temperature value. For a mercury thermometer, you should hold the glass end of the thermometer, which is far away from the mercury column, so that your eyes are at the same level as the thermometer. Then, slowly rotate the thermometer to read the corresponding temperature value when you see the thick mercury column from the front. Be careful not to touch the mercury end of the thermometer with your hands when reading, otherwise it will affect the mercury column reading and cause inaccurate measurement.
