Airtightness Test Instruments, also known as Sealing Test Instruments, Waterproof Test Instruments, or Leak Test Instruments, are used for detecting the sealing properties of a product or component. They are also referred to as Waterproof Test Instruments or IP67 Waterproof Test Instruments, primarily used to assess a product's waterproof capabilities and whether its waterproof level exceeds the IP67 standard. The name of the Airtightness Test Instrument suggests that the testing is conducted using natural gas. Pneumatic valves are a prerequisite for the application of sealing test instruments. Traditional waterproof testing methods involve using water, but this approach has several drawbacks: 1. It is very complex to operate, requiring operators to submerge the product in water, and some products need to be dried after soaking. 2. The presence of oxygen makes it impossible to detect minor leaks. 3. The detection of leaks is largely dependent on the operator's eyesight, leading to potential misjudgments. 4. The testing process is slow and cannot meet the requirements of rapid automation in production. Due to these drawbacks, more manufacturers are opting for more intelligent, faster, and accurate Airtightness Test Instruments. Shenzhen Linglong Technology Co., Ltd. offers a range of six series of sealing test equipment tailored to different testing products and customer requirements. Linglong Technology's Airtightness Test Instruments can not only detect the sealing of small products such as electric toothbrushes, watches, or speakers but also larger industrial products like car battery packs, helium testing, high-voltage tower protectors, and large outdoor speakers.

Bubble Detection Method: Inject a certain pressure of gas into the sealed product, then immerse the product in water (or another liquid) to observe if any bubbles leak out; or apply foam liquid or soap water to the product surface to see if bubbles form. (This method is outdated, inefficient, may contaminate or damage products, lacks accuracy in manual assessment, and cannot be automated.) This was an early method for detecting airtightness, now rarely seen on production lines and replaced by modern airtightness test instruments.

The testing method of the airtightness leak detector aims to confirm the location and leakage rate of the leak in the inspected item, which is maintained by selecting certain medium-scale leak detection methods. Below, I will provide a detailed introduction to the testing methods of the airtightness leak detector. The selection of methods depends on the structure of the inspected item, the economic benefits of leak detection, and the characteristics of the leak detection system. According to different leak detection objectives, different types of airtightness leak detectors are selected for leak detection tasks. 1. Handheld Airtightness Detection Equipment The handheld airtightness leak detector can quickly locate leakage points, is more expensive, and is suitable for bulk work; it is recommended to use leak detection instruments with a precision higher than 1PPM, such as fuel cell helium leak detectors with a 20PPM detection threshold. Note that the airtightness leak detector should be used without wind entering. When using the airtightness leak detector, the following points must be noted: 1. Do not remove the pipes randomly: Under the pressurized condition of the airtightness leak detector, it is strictly forbidden to remove the connector between the instrument and the pressure relief valve. Otherwise, a large amount of compressed air may be blown out, causing harm to people. 2. No squeezing: It is forbidden to step on or sit on the instrument, or place other objects on the instrument.
