Suggested Favorites! How to choose a suitable air tightness tester? Leak Tester Purchasing Guide

Nowadays, in all walks of life, product quality has become a core factor in determining the competitiveness of enterprise brands, especially some high-precision products, the airtightness and waterproof function directly affects the product performance and safety in use.

那么，如何有效检测和把握产品的密封质量呢？Airtightness Tester就是一个很好的选择。Airtightness testing equipment通过压降法原理，可以精确识别产品整体以及各个部位是否存在漏气问题。

其实，许多行业在生产过程中，都会广泛使用Airtightness Tester。例如：

• In the electronics industry, when developing new products or mass production, airtightness checks are implemented for mainframes, displays, and so on;
• The food industry tests various food packaging such as cans and bottled ware to ensure product quality and safety;
• The automotive industry also needs to know the degree of sealing when assembling body and engine parts;
• Medical equipment and instruments that have air leaks may pose a potential hazard for use.

......

Regardless of the industry, mastering the ability to hermetically seal products is an important part of quality assurance and risk reduction. Therefore.选购一款高效易用的Airtight test equipment对企业来说就变得非常重要，本文将从不同角度，给您一个全面且通俗的购买指南。

Ⅰ.Airtightness Tester是如何工作的？

Now let's take a look at the most common principle of airtightness testing - the pressure drop method of testing - and see how it works:

The pressure drop method of detection is by setting a certain pressure difference between the inside and outside of the product, and then observing the pressure change to determine whether there is an air leak.

具体来说，首先我们会将待测产品放入仿形测试工装夹治具里。然后利用气密仪设备向产品内部持续供应一定气压。同时，我们还会用精密的压差传感器去监测产品内外的压强差异变化值。通过分析这些数据，就可以知道是否存在漏气问题了。

Depending on the positivity or negativity of the applied pressure, the pressure drop method of detection is subdivided into positive pressure detection and negative pressure detection.Positive pressure for types that are prone to clogging and leakage(waterproof test for any open, inflatable product)Negative pressure for products with large air leakage areas(for open type products (with holes for pumping))(This makes the pressure inside the product less than the external atmospheric pressure). In addition, both positive and negative mixed pressure detection modes are available for the widest compatibility.

Ⅱ.Why do I need to test for airtightness?

Whether the product is sealed or not directly affects its performance and service life. Only by mastering the airtight state, the enterprise can guarantee the quality of the product.

III.Which businesses need to buy?

Various industries such as new energy, household appliances, auto parts, consumer electronics, medical devices, security lighting, valves and pipelines, wire connectors, etc., use airtightness inspection in R&D, production and quality control.

IV.When should I buy?

It is suitable to arrange testing during new product testing periods, product upgrades, and regular quality inspections.

V.可以在哪购买leak detector?

目前市场上有很多Leak Detector Brands，选择进口仪器，您可以直接到 ATEQ 阿黛凯或其授权渠道选购；如果追求性价比，则可以考虑国产替代仪器如 JCGK 精诚工科等厂家。

VI.How to choose the most suitable model?

Consider the need for testing accuracy, the type of product, and also evaluate various aspects such as price and after-sales service.

VII.What is the approximate price?

airtightness tester属于专业设备，一般我们都需要直接与检漏仪厂家或其授权代理商沟通商谈。而其价格的多少，往往取决于以下几个因素：

Detection range size:The maximum test pressure supported determines the price.

Test accuracy:Supporting accuracy levels down to a few Pa or 0.1 Pa levels affects cost.

Number of test channels:The more samples of the product under test that are tested at the same time, the higher the cost of the equipment will be.

Whether customized workwear is required:Whether or not customized profiling fixtures are required will also add to the implementation costs.

Generally, in the domestic market, testers are available in a wide range of prices, from a few thousand dollars to tens of thousands of dollars.However, in fact, many low-end brands, in terms of technical design and practical application capabilities, may not always be able to fully meet the various needs of each customer.

JCGK is a national brand that has been working in the industry for many years. Although the price of the product is over 10,000 RMB, its testing accuracy and stability are widely recognized. We always adhere to the concept of rigorous research and development, and are committed to providing various industries with stable functions and cost-effective "assured choice".

In contrast, some internationally recognized brands are priced around tens of thousands of dollars to over a hundred thousand dollars though.Such as France ATEQ, Japan cosmos, the United States Uson, etc., but they often have better control in the detection accuracy, stability.

Moreover, some large-scale domestic listed companies often have higher testing needs than the general industry. Directly purchased ATEQ and other imported brands of equipment as standard equipment. This also corroborates the strength of their products from the application point of view.

VIII.Summarize

Whether you choose domestic or imported testing instruments, the most important thing is to clarify their own testing needs, and at the same time, consult senior friends in the industry to avoid stepping on mines, in order to purchase the most appropriate instrument.We believe that if you choose the right brand, you will be able to maximize your work efficiency.
