LaMotte 溶解氧检测试剂盒，50 /盒

LaMotte Dissolved Oxygen Test Kit, 50 tests/kit

颜色滴定法确定溶解氧量

温克勒滴定法测试样品或校准仪表

仪表故障情况下经适备选

此测试是温克勒的叠氮化改性方法，氧气在强碱，氧化锰的存在下，又与碘反应，生成碘。淀粉指示剂滴定标准的硫代硫酸钠溶液来增强的端点。叠氮化消除亚硝酸盐的干扰。检测试剂盒和笔芯包含足够测试试剂50个，氧气含量为10 ppm。

Color titration method determines dissolved oxygen levels

Winkler titration method to test samples or calibrate meters

Inexpensive backup in case of meter failure

This test is an azide modification of the Winkler method where oxygen, in the presence of a strong alkali, oxidizes manganese, which in turn reacts with iodide to form iodine.This is titrated with a standard thiosulfate solution in the presence of a starch indicator to enhance the endpoint. Azide eliminates the nitrite interference. Test kit and refills contain enough reagents for 50 tests at an oxygen level of 10 ppm.
