Many electronic products have a certain gap in the middle of their surfaces. Under certain working pressure effects, water can seep into the interior of electronic products through these gaps, leading to short-circuit failures and other issues. Daily-use electronic products that must be waterproof can be divided into two main categories: one is outdoor use products, which require waterproofing in their working environment, such as outdoor surveillance cameras, GPS navigators, waterproof connectors, communication base stations, and water detection instruments. The other category includes electronic products that may leak due to various factors, such as smartphones, laptops, and digital cameras, which could potentially fall into water during use. How do these electronic products undergo waterproof testing with an airtightness tester? First, design and customize a welding fixture for the product to be tested; then, select an appropriate airtightness tester based on the testing requirements. The airtightness tester will accurately inject compressed air into the test piece, then automatically close the air pump valve, and the relay will accurately control the required time for air swirl balance, followed by closing the relay for the balance function (with the test piece connected to one end of the static balance valve and a non-leaking standard piece connected to the other). Airtightness testing is conducted through a high-precision differential pressure sensor that connects the test piece and the standard piece with the same supply of gas, accurately measuring the differential pressure between the standard piece and the test piece within the required time. This differential pressure is then used to determine the actual gas pressure caused by the leakage of the test piece, thereby determining whether the test piece is leaking. We will help customers develop comprehensive testing plans based on the products they need to test. Many customers consider how to quickly connect the tester to the product and how to transfer product information to other devices when purchasing a waterproof airtightness tester. Shenzhen Linglong High-Tech, in addition to solving these two problems for customers, will pay more attention to the standard settings and process steps. Different products have different processing materials, and we will help you find the appropriate leak detection parameters for the product. Other personalized services include: 1. Providing suitable leak detection methods and plans; 2. Assisting with the design of suitable fixtures; 3. Helping to define leak detection parameters and pass/fail criteria; 4. Assisting in having a more comprehensive process management system.

Waterproof tester is a widely adopted waterproof testing method by electric toothbrush manufacturers, and it is a type of airtightness tester. It uses compressed air as the medium and mainly employs the differential pressure method for testing. The testing results are determined by comparing the pressure differences before and after the testing end and the standard section are balanced (the pressures at both ends are equal before balancing; if after a period of balancing, the standard end's pressure decreases in Wuxi gas flow detection, it indicates that there is a leakage in the workpiece, and the pressure is the leakage value over a certain period). The waterproof tester overcomes various drawbacks of traditional water testing for waterproofing and can effectively eliminate the impact of environmental factors such as temperature and pressure.

Electric toothbrushes are generally sealed as a whole to enhance their waterproof performance. When using a waterproof tester for inspection, a sealing mold tailored to the product's appearance features must be made. The electric toothbrush is then fixed and sealed to form the testing end mentioned above.

As the functionality of watches increases, more and more watches need to be waterproof to maintain them and extend their lifespan. It's essential to conduct waterproof tests on watches to ensure their quality. Waterproof watches come in various levels, including IP67, 3ATM, and 5ATM. Different levels require different testing pressures. For IP67 watches, the test pressure is typically 10.5kpa, which equals the pressure of the product at one meter underwater. For 3ATM watches, the test pressure is usually 300kpa. For 5ATM watches, the test pressure is generally 500kpa. For smartwatches, the current popular method for waterproof testing is to use air pressure for a seal integrity test.
