A fast-response temperature-compensated pH meter

Abstract

This utility model relates to the field of pH meter technology and discloses a fast-response temperature-compensated pH meter, including a pH meter body. A cable assembly is fixedly connected to the top surface of the pH meter body, and a protective assembly is provided on the surface of the pH meter body. Two sets of placement slots are opened on the surface of the pH meter body. This fast-response temperature-compensated pH meter, through the setting of the protective assembly and magnetic attraction assembly, allows the user to open the protective plate during use. Under the action of a torque spring, the protective plate is supported, facilitating user operation. During storage, rotating the protective plate causes the magnetic block on the back of the protective plate to attract to a magnet. At this time, the magnetic attraction force is greater than the torque force of the spring, allowing the protective plate to close. This prevents the display screen from being impacted, scratched, and worn by external objects, extending the service life of the device. Simultaneously, it also prevents short circuits, damage, or malfunctions caused by liquid intrusion.

Description

Technical Field

[0002] pH value, as a crucial indicator of the acidity or alkalinity of a solution, plays a vital role in numerous industries and scientific research. In chemical production, the progress of many chemical reactions and the quality of their products are highly dependent on the pH value of the solution. For example, in pharmaceutical manufacturing, the acidity or alkalinity of drug synthesis reactions directly affects the structure and purity of drug molecules; precise pH control is key to ensuring drug quality and efficacy. In agriculture, soil pH value determines the efficiency of nutrient absorption and growth patterns of crops; properly adjusting soil pH helps improve crop yield and quality. In environmental monitoring, the pH value of water bodies is one of the core parameters for assessing the degree of water pollution and the health of the ecosystem, and is essential for protecting water resources and maintaining ecological balance.

[0003] In existing devices, the display screen and other parts of the pH meter are subject to impacts, scratches, and wear from external objects, which can damage the device and affect its normal use. Therefore, a fast-response temperature-compensated pH meter is proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This invention provides a fast-response temperature-compensated pH meter, which has the following advantages:

[0016] 1. This fast-response temperature-compensated pH meter, through the setting of protective components and magnetic components, allows the user to open the protective plate during use. Under the action of the torque spring, the protective plate is supported by the user, making it convenient for use. When storing, rotating the protective plate causes the magnetic block on the back of the protective plate to attract to the magnet. At this time, the magnetic attraction force is greater than the torque force of the spring, allowing the protective plate to close. This can prevent the display screen from being impacted, scratched, and worn by external objects, extending the service life of the equipment. At the same time, it can also prevent the equipment from short-circuiting, being damaged, or malfunctioning due to liquid intrusion.

[0017] 2. This fast-response temperature-compensated pH meter, through the setting of the cable bundle assembly, allows the data cable to be wound around the cable bundle post during storage. After winding, the cable bundle is pulled to fix the data cable, thereby reducing the space occupied by the data cable. This makes it easier to put the pH meter body and its accessories into a carrying bag or toolbox, making it convenient to carry to different work sites or laboratories. Attached Figure Description
