As major manufacturers have higher and higher requirements for product quality, especially waterproof standards, waterproof testing is also crucial. Therefore, most products that need to meet a certain waterproof standard require one or even a series of waterproof testing equipment to perform operations. As a high-precision tester for waterproof testing,Air tightness detectorThe demand for air tightness detectors has also increased. Nowadays, there are many manufacturers of air tightness detectors, and the price differences are relatively large. Users have a wide range of options to choose from. However, how to choose a suitable product for their own use requires users to compare and choose based on specific circumstances.

Poor quality detectors are used against the sameAir tightness detectorThe data when a workpiece is repeatedly tested is not stable enough. In addition, the test data just after the startup is warmed up is very different from the test data after 1 hour of work. There will also be a big difference between the test data in the morning and the afternoon.When selecting an instrument, the user can repeatedly test the same workpiece at different times (such as just after the instrument is warmed up, after 1 hour of operation, and after 5 hours of operation) to examine the repeatability of the instrument, the influence of ambient temperature, and the thermal stability of the instrument itself.

The following points are provided here for users’ reference:

1. Since the air sealer uses a special control panel, after-sales issues can often only be handled by the manufacturer. Therefore, it is also important to choose air sealers produced by companies with certain strength and strong viability.

2. The user only needs to use the instrument alone for sealing testing, that is, it does not need to be connected to other control systems. You can choose a detector without input, output, or communication interfaces.

3. For workpiece testing that requires strict leakage indicators, be sure to choose one with good quality and high precision.Air tightness detector。

4. It is recommended that for sealing testing with an internal volume greater than 5l, try to choose the flow type, because when the internal volume is large, small leakage is difficult to cause differential pressure changes; for sealing testing with an internal volume of the workpiece less than 5l, you can choose the flow type or the differential pressure type according to the process requirements.

5. When there are many types of testing in the production line, each type requires different parameters (such as inflation time, balance time, pass judgment value). At this time, the user needs to choose an air tightness detector with the [channel] function so that one model corresponds to a set of channel parameters.
