我们提出了闭合误差的概念，作为仪器测量精度的判据，测量仪器的瞬时均方差，以表征测量的重复性和可靠性。
We suggest "error of closure" asa criterion of measuring accuracy and use transient root-mean-square error to ex-press repeatability and reliability of measurement of the instrument.
仪器采用数字显示，并可随时打印记录温度的瞬时值、平均值与最高值。
This instrument has a digital display, which can print the instantaneous, mean value and maximum of measured temperature conveniently.
