CODmax II 重铬酸钾法COD分析仪
-产品优势:
CODmax II是基于重铬酸钾氧化法(符合国家标准GB11914-90)设计的污水COD速测仪,具有性能稳定,维护量小等优势。
- 工作原理:
水样、重铬酸钾、硫酸银溶液(催化剂使直链芳香烃化合物氧化更充分)和浓硫酸的混合液在消解池中被加热到175℃。在此期间,铬元素从VI价被还原成III价,发生变化。颜色改变度与样品中有机化合物的含量成对应关系,所以仪器可通过比色法换算样品的COD值,并可直接显示出来。CODmax II测试废水COD时的主要干扰物为氯化物,可加入硫酸汞去除。
- 应用行业:
CODmax II分析仪可用于污染源污水排口、市政污水进排口、工业废水排口等领域的废水COD检测。
- 仪器特点:
● 经典重铬酸钾氧化法与全新测试技术的结合,使CODmax II在废水COD检测时能够自动计算COD值;
● CODmax II污水COD速测仪采用先进的活塞泵技术和抗腐蚀的管路设计;
● 自动泄露监测;
● 自动状态诊断;
● 自动校准、清洗功能;
● 安全防护面板;
