铜，是应用广泛的重要金属，被应用在很多领域，如：合金、染料、管道、线路等，铜盐可以抑制水中浮游生物或藻类的生长，在饮用水中，铜离子浓度超过1mg/L就会产生苦味。因此我国已把铜离子规定为实施总量控制的指标之一。 该分析仪能够根据现场设定长期无人值守自动连续工作，广泛适用于工业污染源排放废水、工业过程工艺废水、���业污水处理厂污水、市政污水处理厂污水等场合。根据现场测试工况的复杂程度，可选配相应的预处理系统，以保证测试过程可靠、测试结果准确，充分满足不同场合现场需求。
Copper is an important metal that is widely used in many fields, such as alloys, dyes, pipes, lines, etc. Copper salts can inhibit the growth of plankton or algae in water. In drinking water, the concentration of copper ions exceeds 1mg/L. It will produce bitterness. Therefore, China has set copper ions as one of the indicators for the implementation of total control. The analyzer can automatically and continuously work according to the on-site setting for long-term unattended operation, and is widely used in industrial waste water discharge, industrial process wastewater, industrial sewage treatment plant sewage, municipal sewage treatment plant sewage and other occasions. According to the complexity of the field test conditions, the corresponding pre-treatment system can be selected to ensure the test process is reliable and the test results are accurate, which fully meets the on-site requirements of different occasions.
产品原理：
本产品采用分光光度测量方法测定，水样和缓冲剂混合后，在强氧化剂存在下，铜转化成各自的高价态离子，在缓冲溶液和指示剂存在的情况下，高价离子与指示剂反应生成一种带色络合物，分析仪检测此颜色的变化，并把这种变化换算成铜值输出来，生成的带色络合物量相当于铜量。
本产品为单因子参数测试分析仪器。
本方法适用于铜在0-30mg/L范围内的废水。
Product Principle: This product is measured by spectrophotometry. After the water sample and buffer are mixed, in the presence of strong oxidant, copper is converted into its own high-valence ions. In the presence of buffer solution and indicator, high-valent ions react with the indicator. A colored complex, the analyzer detects the change in color and converts this change into a copper output to produce an amount of colored complex equivalent to the amount of copper. This product is a single factor parameter test and analysis instrument. The method is applicable to wastewater with copper in the range of 0-30 mg/L.
