The electronic thermometer can also be called digital thermometer, which is a kind of thermometer for home use, especially for baby care. The general electronic thermometer consists of four parts. The head is a thermo sensitive component. The body is a digital temperature display. Beside it is the power switch button, and the end is the battery box. We should pay attention to the following points in the purchase of electronic temperature.

1. Appearance check.

The electronic thermometer is usually small and beautiful, with smooth surface and no defects.

2. Accuracy examination.

Press the switch button and there is a "LOC" mark on the LCD. Put the thermometer under the tongue for 1 minute. When the "C" mark stops flashing, the reading number is body temperature, which is the body temperature of the mouth. Repeated several times, the oral thermometer should be the same. If not the same, it means the thermometer is not good and it could not be used.

If the oral thermometer exactly the same, you can measure 2-3 minutes in armpit. When the "C" mark stop flashing, the reading number is armpit temperature. Similarly repeating several times, the body temperature under the armpit is the same. The general oral temperature is 1 degree higher than that of the armpit temperature. If the oral temperature is too high or too small, the accuracy of the electronic thermometer is not satisfactory.
