Description

Technical Field

[0001] The utility model relates to the technical field of pure water equipment, in particular to pure water equipment with an online detection function. Background Art

[0002] Ultrapure water refers to water in which the conductive medium is almost completely removed, and the non-dissociated colloids, gases and organic matter in the water are removed to a very low level. Ultrapure water is an indispensable and very important raw material for modern industry. It is widely used in various fields, such as the cleaning of semiconductor raw materials and utensils used in the integrated circuit industry, the preparation of photolithography masks, and the production of other solid-state electronic devices, thick and thin film circuits, printed circuits, vacuum tubes, etc. When preparing ultrapure water, it is generally necessary to first add raw water to the water inlet pipe, and then treat the raw water through four units of pretreatment, reverse osmosis, ion exchange, and terminal ultrafiltration to reduce the conductive medium, non-dissociated colloids, gases and organic matter in the water, so that the resistivity of the treated raw water is greater than 10 megohms.

[0003] In the prior art, in order to detect the water quality in the pure water equipment, the conductivity and resistivity of the water are mostly tested to detect whether the pure water quality meets the standard. In the existing pure water equipment, water flows through both ends of the electrode to measure the resistivity of the water flow and calculate the water quality in the pure water equipment according to the water flow rate. However, in the prior art, some conductive media that has not been processed cleanly may accumulate on the surface of the two sets of electrodes after a long time, which will affect the water quality detection standard.
