Air tightness testers used in different products
Common air tightness testers can be divided into the following three methods:
Bubble Method Test:Apply or spray leak detection fluid to the exterior of the product under test and observe whether the fluid enters the object under test. Representative instruments of the bubble method include water tightness testers, waterproof test boxes, etc., commonly known as water tests.
Waterproof test chamber, also called rain test chamber
Frontages: simple and easy to use, low cost.
Disadvantages: low precision, can only detect large holes, cannot detect small holes, not suitable for detecting high pressure vessels, needs to be dried after product testing is completed , etc., the steps are cumbersome and time-consuming. Manually, this method is suitable for detecting large equipment and components and has limitations.
Testing pressure drop method:Use the pressurization and depressurization method of the product to be tested to test airtightness and observe whether the pressure drops . Representative instruments of pressure drop method include direct pressure air tightness testers, gas flow detectors, etc., commonly known as gas monitoring.
Test scheme of pressure drop method
Advantages: high precision, simple operation, can detecter small holes, cracks and other small flaws, widely used, fast detection speed, even test a product within a few seconds.
Disadvantages: It cannot detect tiny flaws, cannot accurately find the leak point of the inspected product, and must be equipped with a high-pressure booster pump.
Mass Spectrometry Test:This type of air tightness tester applies a vacuum to the product being tested and measures the vacuum decay generated within a defined time. This method makes it possible to detect the smallest leaks by measuring the vacuum drop that occurs. Representative instruments of mass spectrometry include helium mass spectrometer leak detectors, hydrogen mass spectrometer leak detectors, etc., commonly known as helium detection.
Helium mass spectrometer leak detectors on the market
Advantages: high precision, lowt detect tiny leaks and can be used to detect products in high pressure, large volume sealed containers.
Disadvantages: Specialized helium mass spectrometer leak detector is required and the cost is high.
In modern industrial manufacturing, air tightness detectors have become an indispensable tool. The airtightness tester can quickly and accurately detect the sealing performance of the product and detect tiny leaks. This can help factory manufacturers improve product quality and process efficiency, and reduce product failure rates and repair costs.
If you want to ensure that your products meet the highest quality standards, please base your test on the material, shape, size, application scenario, requirements airtightness testing accuracy and budgetsupply. of the product you are testing and other factors to choose an appropriate airtightness detector.

The most comprehensive of the whole network! Various classifications and testing methods of airtightness testing equipment
What are the types of airtightness testing equipment
Hello! To carry out the airtightness test of lithium-ion batteries, we need to prepare an airtightness tester, customize a set of tools and a set of molds which exactly match the lithium-ion battery . The combination can be completed by connecting air. Hose and power supply. Airtightness tester for Lithium-ion battery.
The specific test method is as follows:
1. ConnecPass the airtightness detector and the test tool mold through the air source pipe. The air supply pressure to the air source part is. 0.4-1.2 MPA, cannot exceed this range. Connect the power cord, the required voltage is 220V.
2. Set the test parameters according to the test requirements and select the airtightness detector test program according to the set program.
3. Insert the lithium-ion battery product to be tested and start testing. The instrument will automatically determine whether the product is good or defective based on the parameters we set.
The testing methods of different lithium-ion battery airtightness testers are similar. The only difference is that they are customized according to customer needs. Some customers choose multi-station because of the high production speed. double.Or a testermulti-channel airtightness. Some customers' production lines have low output and may choose single station airtightness tester. However, the testing principles are basically the same, but the selection is different. Since the shapes of lithium-ion batteries are different, the tooling molds are all individually customized.
In industrial production, air tightness testing equipment is widely used. This is a testing instrument used to detect and measure the sealing and sealing performance of various products, to ensure that the tested components do not have water leakage defects or airtightness, and to ensure the quality and life of the product, it can be said that from the mobile phones we use daily to the cars we drive in, airtightness testing is inseparable.
