电子体温表是利用感温元件(通常是用热敏电阻)的电阻随环境温度的变化而变化的原理制成的。电子体温表读数直观,携带方便,小巧新颖,不易损坏,比普通水银体温计更易保管。 一般电子体温表由四部分组成,头部是感温部件,杆身是数字式温度显示器,旁边是电源开关按钮,末端是电池盒和盖。购买电子体温表时要注意以下几点:
Electronic thermometer is the use of temperature sensing element (usually with thermistor) resistance changes with the ambient temperature is made of the principle. Electronic thermometer intuitive readings, easy to carry, small and novel, not easily damaged, easier to store than the average mercury thermometer. The general electronic thermometer consists of four parts, the head is the temperature components, the shaft is a digital temperature display, next to the power switch button, the end of the battery box and cover. When buying electronic thermometer should pay attention to the following points:
