AUTOMATIC CALIBRATION SYSTEM AND METHOD FOR THERMOMETERS AT LOW TEMPERATURES

摘要

PURPOSE: A system and a method for automatically correcting low-temperature of a thermometer are provided to automatically control the temperature of a low temperature maintain unit, and to complete correction until the temperature is naturally risen. CONSTITUTION: A system for automatically correcting low-temperature of a thermometer comprises a low temperature maintaining unit(100), a temperature control unit(200), a temperature measuring unit(300), and a controller(400). The low temperature maintaining unit has a reference thermometer(111) and a target thermometer(112), and maintains a low-temperature state. The temperature control unit controls the temperature of the low temperature maintaining unit. The temperature measuring unit measures the temperature of the reference thermometer and the target thermometer. The controller controls the temperature control unit, and reports the measured temperature.
