Description

一种水质及多离子液体分析仪
技术领域
本实用新型涉及一种水质及多离子液体分析仪，属于测试仪器技术领域。
背景技术
水体内重金属元素离子的测定是水质分析中的一个重要内容，目前大都采用经典的化学滴定分析法测定这些微量元素离子，但化学分析法操作繁琐、且需要经专业人员操作，人工计算；某些条件较好的水质分析部门则使用原于吸收光谱仪，但原子吸收光谱仪价格较贵，安装、使用及维护费用都比较高且不便使用。随着人们环保意识的增强，水体测量越来越重要。水体测试分析的项目众多，常见的有铁、铜、氨氮量、亚硝酸盐、溶氧量以及余氯等等。现有的水体分析仪普遍存在的问题是均为实验室化学滴定分析法人工测试。
发明内容
本实用新型就是针对现有技术的不足特设计一种具有多波长发光二极管的多参数水质分析仪，由多种发光二极管组成的管体，比色管，光接收器，处理电路，显示器，切换开关，比色管座组成，比色管座上放置一个或多个发光二级管，其中发光二级管组成的管体内放置单个或多个发光二级管。
采用这种结构后，就可以准确的测量多种元素，使仪器的测量范围大大扩大，从而极大的减少了水质的测试成本。
附图说明
下面结合附图对本实用新型进一步说明：
图1为具有单个发光二级管的水质及多离子液体分析仪原理示意图；
图2为具有三个发光二级管并附有比色管座的水质及多离子液体分析仪原理示意图；
图3为具有三个管体并附有比色管座的水质及多离子液体分析仪原理示意图。
具体实施方式
发光二极管组成的管体1通过比色管2由光接收器3接收光，其光的大小会随着比色管2中的液体浓度的变化而变化，浓度越低则光就越亮，反之则光就越暗，其变化规律满足郎伯比耳定律。但是因为被测试液体元素是不同的，化学反应呈现不同的颜色。因此如果使用单一波长发光二极管则不能准确满足多种元素测量需要。所以在具体实施中为解决该问题，我们采用由不同波长的发光二极管组合成的管体1根据具体需要放置不同波长的发光二极管。当然也可在比色管座7安置多个单体发光二极管如图3所示。
除上述实施方式外，本实用新型还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本实用新型要求的保护范围内。
