Description

Technical Field

[0001] The utility model relates to the technical field of Karl Fischer titrator equipment, in particular to a Karl Fischer titrator capable of optimizing titration effect. Background Art

[0002] The technical operation of existing Karl Fischer titrators has the following problems: 1. The test data is unstable and inaccurate. Some samples are poorly soluble or the samples are prone to floccules in the Karl Fischer reagent, which are easily entangled on the burette and the sensing electrode, resulting in insensitive probe sensing or even misjudgment, and prone to non-parallel test samples and over-titration. 2. The generation of flocs during the test affects the titration process. The existing solution is to open the reaction bottle cap to clean the flocs, which causes the water outside the reaction bottle to enter the reaction tank during the process, resulting in errors in the test results.
