The development of electronic technology has rapidly promoted the development of waterproof tester technology. Strong manufacturers all use integrated circuit ARM controllers, and the electronic circuits are anti-interference and stable. The power supply provides a reliable guarantee for the test data of the instrument. Now, many small domestic manufacturers use PLC editing programs. Due to the interference of PLC data transmission and transmission to the internal sensor, it is very easy to cause data deviation and distortion, and it is impossible to truly distinguish the detection,Whether the result meets the technical requirements.

The stability and repeatability of the waterproof tester can be tested by the quality tester. Whether the most important product can withstand the verification of the same product at different times. If the test data of the same product at different times is relatively large, the test requirements cannot be met. The waterproof tester can reach the repeatability and stability of 2.5% FS accuracy, reaching the level of similar imported testers.

To choose a reliable instrument, first determine the reliability of the parts of the waterproof tester, the stability coefficient and detection accuracy of the differential pressure sensor and the flow sensor. Decide which instrument you want to buy can meet the requirements. The test accuracy of the differential pressure sensor usually needs to reach 0.01% FS to meet the requirements of high-precision testing. Do you have clear technical parameters for the instrument you purchased?

Different product waterproof testers have different detection methods. Products include metal parts, castings, plastic parts, etc. Each product has a different detection method. Professional researchers and technicians can provide better technology to help customers successfully test products. Sometimes, even if the purchased product is imported, it is the most expensive and the most incorrect method. Not only can the product not be detected, it may also affect the quality of the company's products. Therefore, the method of checking the air tightness is very important.
