Air tightness tester is a non-destructive high-precision testing equipment that uses compressed air as the medium to apply a certain pressure to the inner cavity or surface of the product to be tested, and then uses a highly sensitive sensor to detect changes in pressure to determine the air tightness of the product to be tested.

Since the medium used for testing is compressed air, which is clean and pollution-free, there will be no secondary contamination of the product to be tested during testing.

Therefore, for products that now need to detect air tightness, waterproofness, and sealing, most of them choose non-destructive and high-precision air tightness detectors.

How to operate the non-destructive high-precision air tightness detector?

1. When the product to be tested does not have an inflation hole, customize the jig, tooling and air tightness tester corresponding to the product to be tested; if the product to be tested has an inflation hole, only a quick connector and an air tightness tester are needed

2. The instruments and equipment are connected to the power supply (AC220V±15%, 50HZ) and gas source (0.4~0.8MPa, clean and dry);

3. Turn on the instrument and set the parameters of the detection program;

4. Turn on the "meter zero" function to ensure that the test air pressure is normal;

5. Connect the product to be tested and the testing instrument/equipment through the air tube;

6. Start the program and start inflating, stabilizing, testing, and deflating;

7. The instrument automatically determines whether the tested product is qualified according to the program. The device displays OK as a qualified product and NG as a defective product.

8. The program ends and the instrument stops moving;

9. Take out the product to be tested, put in the next test product, restart the program, and start testing.

Advantages of air tightness detection:

A. Lossless, fast, clean, easy to operate;

B. High sensitivity and accurate results;

C. Strong scalability, repetitive process, suitable for automated machines;

D. The results are traceable

E. Economical, practical and cost-effective.

Hairuis has specialized in air tightness testers for fourteen years and developed an intelligent sealing detection system. This system uses microchip technology and combines the patented algorithm of "intelligent pressure difference" to be used in mobile communications, smart wearables, fuel vehicle/electric vehicle accessories, hydrogen energy,It has produced many successful product testing cases in industries such as home appliances, audio, security lighting, medical equipment or wire harnesses, and has also helped customers improve the airtightness of their products, making Hirays's contribution to the airtightness detector industry.
