混凝土保护层厚度测定仪是检测混凝土保护层厚度的重要仪器,通过对混凝土保护层厚度测定仪的校验,评定其示值误差的不确定度,确保混凝土保护层厚度测定仪示值的准确性,保障保护层厚度检测结果的可靠性。本文阐述了混凝土保护层厚度测定仪示值误差的校准过程,并通过建立数学模型、评定标准不确定度和扩展不确定度,得到混凝土保护层厚度测定仪示值误差的不确定度。
The concrete cover thickness tester is an important instrument for measuring the thickness of concrete cover. By checking the concrete cover thickness tester, the uncertainty of indication error is evaluated to ensure the accuracy of the concrete cover thickness tester. , To ensure the reliability of the thickness of the protective layer test results. In this paper, the calibration procedure of indication error of concrete cover thickness tester is expounded, and the uncertainty of indication error of concrete cover thickness tester is obtained by establishing mathematical model, evaluating standard uncertainty and expanding uncertainty.
