摘　　要：温度巡检仪用于环境实验设备温度参数的校准。本文通过对温度巡检仪构成原理及相关性的理论分析,得出不同温度通道之间相关性由两个因素决定:(1)各通道不同的传感器;(2)测量电信号用电测仪表。本文主要研究二者组成的温度测量通道之间的相关性,通过实验估算出一种型号为PR205AF的巡检仪不同温度通道之间的相关系数为0.375。Temperature patrol detector is used to calibrate the temperature parameters of environmental-laboratory equipment.In this paper,the composition principle and the correlation of the temperature inspection instrument are analyzed,it is concluded that the correlation between different temperature channels is determined by two factors:(1)Different sensors of each channel;(2)Electrical measuring instrument for measuring electrical signals.The correlation between the two temperature measurement channels was mainly studies in this paper,the experiment showned that the correlationc coefficient between different temperature channels is 0.375.
