Product selection and use analysis of air tightness tester

With the development of the market and the improvement of the economy, the requirements for quality have more standardized requirements, and the requirements of air tightness testing are more and more adopted by various manufacturers, which is a good advantage to promote the development of air tightness testing industry.

The development of the market economy has also promoted the development of instruments. More companies have been put into this sale, resulting in uneven products, many manufacturers of air tightness testing instruments and great differences in prices. The imported instruments such as Flohr Rishi in Germany, ATEQ in France, Cosmo in Japan, and some domestic units. It can be said that how to choose the right detector is the most important. The most research and development company and leak detector company will give you some suggestions.

1. the stability and repeatability of the instrument test a quality tester, the most important product can withstand the verification of the same product at different time. If the data of the same product detected at different time is large, it does not meet the requirements of testing. The remote intelligent leak detector can realize the precision of repeatability and stability to 2.5%F.S. Degree, at the same level as the import detector.

2. the development of electronic technology has rapidly promoted the development of air tightness detection technology. All the powerful manufacturers use integrated circuit ARM controller. The anti-jamming and stability power supply of electronic circuit provides reliable guarantee for the instrument test data. Now there are many small factories in China using PLC to edit the program, because of PLC data The interference of transmission and transmission to internal sensors is very easy to cause data deviation and distortion, and can not truly distinguish whether the test results meet the technical requirements.

3. the selection of product components, a reliable instrument, the first is the reliability of the instrument components, the stability coefficient of the differential pressure sensor and the flow sensor itself and the detection precision determine whether the instrument you purchased can meet the requirements. The test precision of the differential pressure sensor usually reaches 0.01%F.S to meet the high precision test. Does the purchase instrument have clear technical parameters?

4. the selection of detection methods, the domestic enterprises do not have many original R & D enterprises, different product detection methods are different, the products have metal parts, casting parts, plastic parts and so on. Each product has different testing methods. Professional researchers and technicians can provide better technology to help customers to test products successfully. Sometimes even if the product is imported, the most expensive, the wrong way, the product can not be detected not only, but also may affect the quality of the company's products, so it is very important to check the air tightness method.

The far intelligence leak detector combines the advantages of the leakage meter at home and abroad, combined with the original research and development, improves the performance of the product greatly, develops the side leakage instrument suitable for the domestic production line, and studies the gas tightness test method for a long time, and can better realize the gas tightness test. At the same time, in order to make the customers better and use the leak detector more quickly, it has developed a fast stainless steel quick joint and a leak detection and plugging joint to improve the detection efficiency. A810, A830, A850 and other models of air tightness detector manufactured by far wisdom company can cooperate with non-standard testing equipment to optimize the testing site of customers.
