The evolving new technology has brought a very strange thermometer, which can be called a Body Thermometer or a dot matrix thermometer. This thermometer is only the size of a business card, 6 to 7 cm long and 0.5 cm wide. It is covered with neatly arranged dots with numbers. After the body temperature test, the dots below a certain value will all be darkened, and the colors of the other dots will remain unchanged, and the user can determine the body temperature according to the above changes.
Body Thermometer Characteristics
The thermometer is not expensive, small in size, easy to carry and store, and has very little pollution. It is especially suitable for medical institutions and can be used once to avoid cross infection.
