摘要
按照JJG880-2006《浊度计检定规程》对浊度仪进行示值误差的检定,对检定结果的不确定度来源进行了分析,对各不确定度分量进行了评定并合成了标准不确定度。当浊度仪的示值误差为5.0%时,检定结果的扩展不确定度U=3.8%(k=2)。
The measurement error of the nephelometer were verified according to JJG 880 - 2006 the Verification Regulation of Nephelometer. The sources of the measurement uncertainty in verification process were analyzed and evaluated, and the combined standard uncertainty was obtained. The expanded uncertainty of the verification result was 3.8% （k = 2） when the the nephelometer was 5.0%.
