近年来,红外测温仪作为非接触式温度测量仪器的主力军,已越来越广泛地应用于电气设备、石化设备和其他工业设备的状态监测中,对于该类仪器的检定和校准越来越受到各省市级计量单位的重视。笔者发现,在检定或校准该类仪器时,时常会出现示值不稳,时大时小或者偏离正确值较大的现象。对此,笔者进行了以下原因分析。一、黑体的影响红外测温仪的检定和校准设备主要为黑体和标
In recent years, as a main force of non-contact temperature measuring instruments, infrared thermometers have been more and more widely used in the condition monitoring of electrical equipment, petrochemical equipment and other industrial equipments, and more and more applications for the verification and calibration of such instruments The more subject to the measurement units at the provincial and municipal levels. I found that in the test or calibration of such equipment, often appear instability, when the big small or deviate from the correct value of the larger phenomenon. In this regard, I conducted the following analysis. First, the impact of black body Infrared thermometer calibration and calibration equipment mainly black body and standard
