Huate Technology and Runchi Engineering applied for patents related to water quality sensors, capable of detecting water quality with adjustable length, followed by centrifuge dehydration after use.

On March 28, news emerged that the National Intellectual Property Administration’s information shows that Nanjing Huatian Technology Development Co., Ltd. and Nanjing Runchi Engineering Technology Co., Ltd. applied for a patent titled “A Chemical Sensor and Preparation Method for Water Quality Detection.” The application publication number is CN121741099A, application number is CN202610068056.3, publication date is March 27, 2026, application date is January 19, 2026, inventors are Gao Wei, Xing Jiehua, Gu Lei, patent agency is Nanjing Subo Intellectual Property Agency (general partnership), patent agent is Zou Yufeng, classification numbers G01N31/00, G01N33/18.

The patent abstract shows that the invention relates to the field of water quality detection technology and discloses a chemical sensor and preparation method for water quality detection, including a handle and a chemical sensor body. The upper side of the handle is rotatably equipped with a rotating column, the upper side of the rotating column is fixedly connected to a mounting rod, above the mounting rod is an installation ring, the chemical sensor body is positioned above the installation ring, the inner side of the installation ring is plugged with a connecting rod, the chemical sensor body is fixedly mounted at the upper end of the connecting rod, both sides of the installation ring internally define a cavity, inside the cavity is a limiting mechanism that restricts the movement of the connecting rod relative to the installation ring, and the side wall of the handle has a through groove. This chemical sensor for water quality detection and preparation method can adjust the overall length of the sensor, making it convenient to detect water quality at different depths, and can centrifugally dehydrate the entire sensor after use, effectively avoiding water sample residue.
