本文介绍一台工业流程用间歇式自动成份分析仪。仪器根据光电比色原理制成。以测量具有大量机械杂质和浓度很高的硫酸锌水溶液中全铁含量为例,技术指标为:测量范围0～2克/升,精度10级,间歇测量周期135秒,测量滞后时间110秒。可从距罐口3米左右深处自动提取比重为1.5左右的液体试样,快速送到几十米外的主机进行分析。主机具有过滤、定容、稀释、着色等试样预处理功能。采用特
This article describes an industrial process with intermittent automatic component analyzer. Instrument according to the principle of photoelectric colorimetric made. Taking the measurement of total iron content in aqueous solution of zinc sulfate with a large amount of mechanical impurities and high concentration as an example, the technical indicators are as follows: the measurement range is 0-2 g / L, the accuracy is 10 levels, the intermittent measurement period is 135 seconds, and the measurement lag time is 110 seconds. Can be taken from the tank mouth about 3 meters deep automatically extract the proportion of about 1.5 liquid samples, quickly sent to dozens of meters away from the host for analysis. The host has a filter, constant volume, dilution, coloring and other sample pretreatment. Use special
