Description
The technical field is as follows:
the invention relates to the technical field of thermometer production equipment, in particular to a hot water bath tank for mercury-free thermometer production.
Background art:
thermometers are tools that can accurately determine and measure temperature. Most of medical thermometers for measuring the temperature of a human body or the temperature of an animal are glass thermometers, and the thermometers realize temperature measurement by utilizing the principle that a temperature measuring medium expands with heat and contracts with cold. As mercury in the mercury thermometer has toxicity, liquid alloys such as gallium and indium are adopted to replace mercury to serve as temperature measuring media in the market at present, and the mercury-free thermometer is manufactured.
The method comprises the steps of firstly putting the mercury-free thermometer into water with fixed temperature, enabling a temperature measuring medium of the mercury-free thermometer to rise to a scale at the temperature and mark the scale, then putting the scale into water with another fixed temperature to obtain a scale corresponding to another temperature, equally dividing the two scales according to the temperature difference of different fixed temperatures, and sticking corresponding scale strips according to the corresponding scales. In this in-process, the water bath is carried out in the thermostat of fixed temperature to no mercury thermometer puts into so that medium temperature rises, because there is the difference in temperature in the water in no mercury thermometer and the thermostat, can lead to the temperature to reduce after no mercury thermometer puts into the aquatic to because environmental impact, change can appear in inside temperature, and there is the distance between sensor and the heater of inside measurement temperature and the thermometer, can lead to inside temperature to appear great unbalance phenomenon, thereby influences the degree of accuracy of scale.
