Abstract:This article introduces the optimum options for temperature test system of sensors for automatic distillation apparatus. It has been proved that after the optimum design，the temperature sensor for automatic distillation apparatus can be used to replace the glass thermometer and indicate the temperature，and it has greatly improved its resolution and accuracy. It has the same temperature lag, effect of revealed liquid column and precision as the distillation-range glass thermometers, and it further improves the test accuracy and reliability.
