Selection of air tightness detector

presentDevelopment of air tightness detectorThere are many manufacturers, and the price difference is also relatively large. There is a wide range of choices for users, but how to choose

The products suitable for their own use need to be compared and selected by users according to the specific situation. When selecting instruments, users can use the same

Each workpiece is tested repeatedly at different times to checkgasDensity detectorThe repeatability of the instrument, the influence of ambient temperature and the thermal stability of the instrument itself are discussed.

The main approaches are as follows:

1、The user can choose the detector without input and output ports, and use the instrument to test the tightness,防水检测设备There is no need to communicate with others

Control system.

2、When the inner volume of sealing test is more than 5L, the flow type should be selected as far as possible; When the inner volume of the workpiece is less than 5L, the sealing test is not necessary

Flow type or differential pressure type can be selected according to process requirements.

3、When there are many kinds of products to be tested in the production line, the parameters required for each variety are different. At this time, the user needs to select the product with channel function


4、For the workpiece detection with strict requirements of leakage index, it is necessary to select the one with high precision and good qualityAir tightness testing equipment

5、Because the airtight instrument uses special control board, it is very important to choose the airtight instrument produced by enterprises with certain strength and strong viability


The data of the detector with poor quality is not stable when repeatedly testing the same workpiece. In addition, the data of the detector just after starting up and preheating is not consistent with the work

There is a big difference in the test data after one hour, and there is also a big difference between the test data in the morning and in the afternoon.


Shenzhen hairuisi Automation Technology Co., Ltd. has been committed to air tightness testing, waterproof testing and leakage testing equipment for many years

The technology of R & D and production is relatively mature. The air tightness detection degree of hiris device can reach 0.1pA. And launched a number of models

Special testing equipment, such as automobile cylinder device air tightness testing equipment, pipeline valve device tightness testing, grounding device waterproof

Testing, etc., won a large number of customers, and said that the airtightness testing equipment, waterproof testing equipment stability is very good
