Research on miniature fixed point apparatus of 37 ℃
Currently,comparison method is used to calibrate clinic thermometers.The calibration system includes electrical measuring instruments,temperature sources,standard thermometers,etc.The equip-ment composition is complex,with poor portability and complex system operations.Thus,it is difficult to calibrate clinic thermometers on-site.37 ℃ is the temperature point near the human body tempera-ture.Designing and developing the portable 37 ℃ fixed point Apparatus to reproduce 37 ℃ by using the fixed point method.Reproducing the 37 ℃ temperature plateau and research the temperature plateau re-tention time,stability,and reproducibility.This provides a stable and reliable standard device for on-site calibration of clinic thermometers,and can be used as a miniature secondary fixing device in conjunction with other temperature fixing point devices.
