An unpublished guide to purchasing a waterproof tester,Air tightness test, internal secrets of IP waterproof detector manufacturers

First, you need to understandWaterproof testWhat does it do?And its waterproof test method, and how the IP waterproof test standard adopted recently is defined, the currently popularWaterproof testerWhat's the main thing?

Waterproof tester, also known as air tightness tester, sealing tester, air tightness leak detector.The main function is to detect the waterproof ability of the product, excellent sealing performance, IP waterproof testing and grade identification, and leakage amount.

Mainly used in: mobile phone waterproof testing, camera waterproof testing, connector air tightness testing, battery pack air tightness leak detection, bracelet IP66 waterproof testing, and higher-level IPx waterproof level testing and identification, online tightness testing, flow testing, and other fields.

The times are advancing, and people's requirements for waterproofing are getting higher and higher. Due to the better development of air tightness and waterproof testers, many waterproof tester manufacturers have emerged. Among them, Hirays Waterproof Testing has ten years of testing and R&D experience, and has a large waterproof testing group. It is one of the few popular air tightness testers and waterproof tester production, R&D and sales companies.

Among the many waterproof detector manufacturers, how to choose depends on the following points.

1. Requirements for waterproof detection accuracy!

Accuracy: inWaterproof tester, the air tightness leak detector industry is always the first, especially the IPx6 waterproof test of small components or the higher level IP waterproof test level, which is particularly obvious.In air tightness testing and waterproof testing industry, the unit of accuracy generally adopts Pa.For example, the waterproof detection of bracelets requires very high accuracy of the waterproof detector used.Since the bracelet is relatively small and the internal space is very small, a waterproof tester is used for testing. Since it only leaks a little bit of air, it has already reached the internal and external pressure balance. If the accuracy is not high, it is impossible to accurately detect the IPX6 and IPX7 waterproof levels of the bracelet.The new air tightness tester of Shenzhen Hirays Automatic Technology adopts unique pneumatic technology. The internal space is only (1.5cc), which can effectively ensure the accuracy of the test. The maximum has exceeded 0.1PA, which means that only bubbles as big as a pinhole can be accurately detected every minute.

2. Requirements for the stability of waterproof detectors.

Waterproof detectorThe stability is related to the testing quality of the product.Therefore, an excellent waterproof testing equipment and air tightness testing equipment have better stability, which is an important technical indicator for its market share.Therefore, how to ensure the stability of the waterproof test is extremely important. The important factor is temperature. Changes in humidity will cause the sensitivity of the sensor. Then the waterproof test equipment should have a temperature compensation control system so that changes in temperature will no longer cause instability in the test. This is the unique air tightness test technology of Hirays Waterproof Testing.

3. The efficiency of waterproof testing, that is, the speed of IPX waterproof level testing.

With the development of industry and the increase in costs, many companies have put efficiency first.So the air tightness, waterproof testing, and sealing testing industries are no exception.The air tightness and waterproof tester that can realize automated detection and intelligent detection has attracted more attention from all aspects.Therefore, the waterproof tester should have the function of automatic air tightness leak detection.

4. The waterproof tester is intelligent.

With the development of artificial intelligence, a highly intelligent air-tightness and waterproof tester has obviously attracted more attention from customers.Such as networking, remote control and other humanized designs.Jiadi facilitates the tracking, archiving, analysis and other needs of waterproof test data.

5. Positive and negative pressure functions of waterproof detector

As the complexity of products increases, some products are not suitable for positive pressure testing, and some are not suitable for negative pressure testing. Moreover, air tightness and waterproof detectors with integrated positive and negative pressure functions are the needs of the market and can be suitable for more and more complex IPx waterproof tests and air tightness leak detection conditions.
