Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring equipment, in particular to a self-stirring device of a dissolved oxygen measuring instrument. Background Art

[0002] The dissolved oxygen meter is a device used for water quality testing, and dissolved oxygen is a very important indicator of water quality testing. Its practical applications include water environment monitoring, industrial production, fisheries, sewage and wastewater discharge control, and laboratory testing of biological oxygen demand (BOD).

[0003] When using a dissolved oxygen meter to detect water quality, it is necessary to insert the probe into the water to be tested for measurement. However, when the electrode contacts the water, the electrode will consume the oxygen in the water, causing the oxygen concentration on the probe surface to drop instantly. Therefore, the water to be tested needs to be corrected. The correction method commonly used in laboratories is to directly stir the water to be tested with a handheld probe. Directly using the probe to stir in the water is prone to collision between the probe and the inner wall of the container, which can easily cause damage to the probe. At the same time, relying solely on the probe to achieve stirring also results in poor stirring effect. Insufficient stirring will also affect the accuracy of the test results, resulting in reduced credibility of the experimental results. Therefore, the utility model proposes a self-stirring device for a dissolved oxygen meter to solve the above problems. Utility Model Content
