Alternative to the water immersion method, the air tightness tester has become the preferred solution for waterproof testing of products.

With the rapid changes in science and technology and the growing needs of users, the product's various functional indices must be constantly improved, and dustproof and waterproof ability, has become an important indicator to measure the overall performance of a product. At the same time, the waterproof performance of the product testing methods are also constantly upgraded.

For a long time.The industry mostly uses the water immersion method (i.e., soak method, the product under test is directly soaked in water to observe whether there are bubbles, so as to determine the sealing of the product) to carry out waterproofing testing.. However, this method is lengthy and inefficient.one unitWaterproof Test EquipmentProduct validation can usually only be accomplished on a case-by-case basis, which does not meet immediate capacity needs.

And as the emergingAirtightness TesterIt can use gas to load the product quickly through a specialized pneumatic control system, and determine whether the sealing is intact through the pressure attenuation of the leakage value.The waterproof performance of the product can be verified in a more scientific and efficient way by collecting precise data.one unitAirtightness testing equipmentRolling inspection of multiple products can be accomplished quickly in a very short cycle, significantly improving inspection efficiency.

So what are the other unique advantages of this new, up-and-coming airtightness testing technology? The following content will provide you with a comprehensive analysis.

1. High detection accuracy:

Air tightness testing equipmentUtilizing a highly sensitive pressure sensor, it is possible to detect extremely small gas leaks. Accuracy resolution is as high as 0.1 Pa (JCGK). Differential Pressure InstrumentsThe detection resolution can be as high as 0.1Pa), far exceeding the traditional water immersion method. Through accurate measurement, the waterproof performance of the product can be more accurately assessed and verified.

2. Safer and more reliable:

Compared to the traditional water immersion method, gas tightness testing is safer as it uses gas as the medium for testing. It does not pose risks such as flooding and short-circuiting to the product and protects the integrity and electrical performance of the product.

3. Non-invasive properties:

Airtightness TesterIt is a non-destructive testing method that does not cause any mechanical damage or side effects to the product. Manufacturers can perform the test with confidence without worrying about damage to the product or compromised quality.

4. Controllability and quantitative analysis of leakage rates:

Airtightness TesterExperimental data can be recorded and calculations can be used to quantify the leakage rate of a product. This allows manufacturers to accurately assess the IP-rated waterproofing performance of their products and make necessary improvements and optimizations.

5. Flexibility and integration with other test methods:

Air tightness testing can be used in conjunction with water immersion, vibration and other test methods to achieve a more comprehensive verification of product protection performance. Through the comprehensive analysis of multiple testing methods, manufacturers can gain a more comprehensive understanding of the performance of their products under different environmental conditions.

Having said all the advantages, how does airtightness testing work? The technical principles and basic process can be summarized as follows:

1. In the first step, the product to be inspected is placed in a closed inspection chamber (tooling);
2. In the second step, the gas source system is used to fill the detection chamber with a gas of a certain pressure (e.g. compressed air, nitrogen, helium, etc.);
3. In the third step, after shutting off the gas source and sealing the inspection chamber, the pressure inside the chamber is monitored by high-precision pressure sensors for subtle changes in pressure over time;
4. Step 4: ObservationAirtightness TesterDisplay interface, if the pressure is rapidly decaying, it means that the product has poor airtightness and leakage; if the pressure is stable, it means that the product has good airtightness.

Through the technical process described above, theAirtightness TesterIt realizes "non-destructive" inspection of the product without touching the inside of the product, avoiding the risk of damage; at the same time, the inspection data is accurate and can be analyzed "quantitatively".

Summarize

Compared with the traditional water immersion method, airtightness testing, as a more precise means of waterproof verification, has excellent characteristics such as high testing accuracy, safe operation and no damage. It is being more and more widely used in the field of waterproof testing of products, which is not only safer and more precise, but also represents a new direction of testing technology.
