                Hua'an is a clinical thermometer manufacturer
                Thermometer is a maximum thermometer, it can record the maximum temperature which the thermometer was measured. Thermometer after use should be "back to the table," that is holding the upper thermometer down firmly jolt, has been promoted to make the mercury tube, back vacuole. Other thermometer must not swinging, which is a major difference with other liquids thermometer thermometer.
                Development:
                The first thermometer: A thermometer is the first Galileo in the 16th century invention. It was not until 300 years later designed and easy to use, reliable thermometer.
                Mercury stored in the end of the mercury ball. When mercury is heated, it will swell, rising along the very narrow glass tube. Therefore, small changes in temperature will lead to a substantial increase in the glass tube of mercury. After the amount of body temperature, swinging too hard thermometer, the mercury back into the mercury ball.
                1714 - 1988
                In 1714, Gabriel Fahrenheit developed a set scale in the freezing point of water and the human body temperature range of mercury thermometers. A Dutch doctors use it to heat the patient's temperature, but the thermometer is still too great, most doctors did not quickly use it.
                In 1868, the German professor who published a paper "disease and hypothermia," a book, the book of the 25,000 cases recorded in the patient's body temperature changes, and the size of his thermometer is used twice Orr Bert thermometer, each takes 20 minutes to record the temperature!
                Later, Robert Orr in 1867 designed a quick and accurate measurement of temperature, length of only about 15 cm thermometer. Unfortunately, the thermometer came too late Bert Orr, Carl Wen Deli Xi failed to provide help.
                After 1980, invented a talking thermometer. Membranous LCD thermometer showing normal body temperature when in green, yellow fever presents, fever red.
                1988, appeared electronic thermometer breathing pulse can telemetry.
