对JJG(苏)117-2010《总磷在线自动监测仪》中示值误差的测量不确定度进行评定[1]。分析了测量不确定度的来源,建立了数学模型,并对测量不确定度的各个分量进行计算,最后合成求出仪器示值误差的不确定度和扩展不确定度。
The measurement uncertainty of indication error in JJG (Su) 117-2010 “Total Phosphorus Online Automatic Monitor” was evaluated [1]. The source of measurement uncertainty is analyzed, the mathematical model is established, and the components of measurement uncertainty are calculated. Finally, the uncertainty and expansion uncertainty of instrument indication error are obtained synthetically.
