What are the errors of air tightness detectors, and how to correctly choose air tightness detectors to detect and identify sealing, waterproofing, air tightness, and IP protection levels

How to choose an air tightness detector

nowAir tightness detectorThere are many manufacturers, and the price differences are relatively large. Users have a wide range of options to choose from. However, how to choose the product that is suitable for their own use requires users to make comparisons based on specific circumstances.

When selecting an instrument, users can test the same workpiece repeatedly at different times to test the repeatability of the instrument, the influence of ambient temperature, and the thermal stability of the instrument itself.

The main ways are as follows:

1. Use the instrument alone for sealing testing and do not need to be connected to other control systems.

2. When the internal volume of the sealing test is greater than 5l, the flow type should be selected as much as possible; and when the internal volume of the workpiece is less than 5l, the flow type or the pressure drop type can be selected according to the process requirements.

3. When there are many types of testing in the production line, each type requires different parameters. In this case, the user needs to choose an air tightness detector with a wide air pressure function.

4. For workpiece testing that requires strict leakage indicators, be sure to choose an airtight detector with good accuracy and high quality.

5. Since the air sealer uses a special control panel, it is important to choose air sealers produced by companies with certain strength and strong viability.The data of poor-quality detectors are not stable enough when repeatedly testing the same workpiece. In addition, the test data just after preheating is very different from the test data after 1 hour of work. There will also be a big difference between the morning and afternoon test data. This situation does not exist with the Hirays air tightness detector, because the Hiraysi air tightness detector uses a precision temperature control system that can communicate with the outside temperature and air pressure. Therefore, there are no factors that affect the air tightness and waterproof detection accuracy.
