clinical thermometer chinese manufacturer

clinical thermometer chinese manufacturer

Hua'an is a clinical thermometer chinese manufacturer,clinical thermometer is a maximum thermometer, it can record the maximum temperature which the thermometer was measured.
clinical thermometer , also known as " medical thermometer ." Working substance is mercury thermometer . It is much larger volume than the volume of the bubble at the capillary tube . Bubble in mercury, due to the influence of body temperature , resulting in a slight change in the volume expansion of mercury , so that the length of the inner tube of the mercury column changed significantly . Usually the change in body temperature between 35 ? to 42 ?, so the scale of the thermometer is usually 35 ? to 42 ?, and the range and degree of each divided into 10 parts , and therefore the thermometer accurate to 1 / 10 degrees. The lower portion of the thermometer near the bubble point of the neck is a narrow curved neck , when the measured temperature , the mercury vacuole , heat volume expansion of mercury by the neck portion rises to the tube to a position, when the temperature reached thermal equilibrium mercury column constant. When the thermometer away from the body , the outside temperature is low, the volume contraction of mercury cold , disconnect the narrow curved neck portion , so that part has been promoted to the mercury back in the tube does not come back , when the mercury remains in contact with the human body achieve a high degree .
Currently ordinary thermometer is gradually being replaced by electronic thermometers , electronic thermometers have a temperature measurement speed, non-contact , etc., are being gradually into the mass people 's home.
