Gas Tightness Tester VS Gas Flow Tester: An article to understand the difference between product leakage and plugging detection

在工业生产中，质量检测就像是产品的「体检」。今天，我们来聊聊两个常见的「体检神器」——Air tightness testercap (a poem)Gas Flow Detector。这两个设备虽然看起来很像，但各有各的「绝活」。让我们一起来揭开它们的神秘面纱吧！

First of all, we have to understand that both devices are designed to ensure the quality of the product, but they do not have the same focus of inspection.

Air tightness tester的任务是测漏。它要找出产品有没有不该有的「漏洞」。 It's like checking a bucket for leaks.

Gas Flow Detector是用来测堵的。它要确保该通的地方是不是真的通了。 It's like checking to see if a straw is clogged.

Air tightness tester：密封性检测专家

想象一下，Air tightness tester就像是一个细心的侦探，专门找出产品中的「漏洞」。

How does it work?

An airtightness tester determines whether a leak exists by applying a certain amount of pressure to the object under test and then measuring the change in pressure. If the pressure drops faster than a preset standard, a leak is indicated.

What are the main areas of use?

It comes in handy in automotive parts shops, electronics production lines, medical device laboratories, and even food packaging plants, wherever there can be no "leakage".

Instrument characteristics:

Air tightness tester能够检测出肉眼难以发现的微小泄漏，对于保证产品质量和安全性至关重要。

Gas Flow Detector：通畅性检测专家

如果说Air tightness tester是在找「漏」，那Gas Flow Detector(also known as流量型气密性测试仪）就是在找「堵」。它就像是一个尽职尽责的管道工。

Capillary Flow Clogging Test

How does it work?

Gas Flow Detector通过向被测对象施加一定的压力或流量，然后测量气体流速或流量的变化来判断是否存在堵塞。如果流速或流量明显低于预期，则表明存在堵塞问题。

What are the main areas of use?

Piping system manufacturing plants, filter production lines, medical device shops, and all types of products that need to be kept flowing.

Instrument characteristics:

Gas Flow Detector能够有效识别产品内部的堵塞问题，对于确保产品功能正常发挥具有重要作用。

The difference between the two

While the two devices may look similar, they can work very differently:

Test Purpose:

• Air tightness tester旨在发现泄漏，而Gas Flow Detector旨在检测堵塞。

How it works:

• Air tightness tester主要关注压力变化，Gas Flow Detector主要关注流量变化。

Criteria for judgment:

• For airtightness testing, stable pressure or minimal decay is considered satisfactory;
• For the clogging test, sufficient flow through is considered satisfactory.

Pressure setting:

• Airtightness testing usually requires high pressures to detect small leaks;
• Blockage testing tends to be low pressure and primarily confirms the presence of a pathway.

Test time:

• Airtightness testing usually takes a long time, especially when detecting small leaks;
• Clogging tests are generally quick, just make sure there is traffic going through.

Data analysis:

• Airtightness testing looks at the rate of pressure change or leakage;
• Clogging tests focus on flow values.

How do I choose between these two devices?

Which 'artifact' you choose depends largely on your product features and needs:

担心漏气漏液？选Air tightness testerThe

担心堵塞不通？选Gas Flow DetectorThe

Worried about both? Then both!

Interestingly, sometimes these two 'miracle devices' can work together to solve cases. For example, when testing complex medical devices, it is necessary to make sure that certain parts do not leak and other parts do not get clogged, and this is when the two devices need to come together.

Summarize

Air tightness testercap (a poem)Gas Flow Detector就像是质量控制的左右手。一个保证不漏，一个确保通畅。正是有了这些精密的仪器，我们才能生产出更安全、更可靠的产品。

Remember.In industrial production, there is no best equipment, only the most suitable method. Choosing the right test equipment and using them correctly is the key to improving product quality. With the advancement of technology, these equipments are being upgraded to add to the development of China's manufacturing industry.
