甲醇可燃气体报警仪校准结果不确定度评定

Evaluation of Uncertainty of Calibration Result of Methanol Combustible Gas Alarm

本文以甲醇可燃气体检测报警仪为例,用空气中甲烷对其示值误差校准,分析检定结果的不确定度来源,并对各分量进行评定。评定参数和过程合理,对计量工作者和相关仪器使用单位具有很好的参考价值。

This paper takes methanol combustible gas detection alarm as an example,uses the methane in the air to calibrate the error of its indication value,analyzes the source of the uncertainty of verification results,and evaluates each component.The evaluation parameters and process are reasonable,and it has a good reference value for metering workers and related instrument users.
