In industrial production, quality testing is like a "medical checkup" for products. Today, let's talk about two common "medical checkup devices" - gas tightness tester and gas flow detector. Although these two devices look very similar, each has its own "specialty". Let's unveil their mystery together!
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.
The task of an air tightness tester is to detect leaks. It has to find out if there are any 'holes' in the product that shouldn't be there. It's like checking a bucket for leaks.
A gas flow detector is used to measure blockages. It's to make sure that the area that should be open is not actually open. It's like checking to see if a straw is clogged.
Airtightness Tester: Seal Testing Specialist
Imagine an airtightness tester as an attentive detective specializing in finding 'holes' in a product.

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:
The ability of an air tightness tester to detect tiny leaks that are difficult to detect with the naked eye is critical to ensuring product quality and safety.
Gas Flow Tester: The Expert in Patency Detection
If an air tightness tester is looking for "leaks", then a gas flow tester (also called a flow type air tightness tester) is looking for "plugs". It is like a responsible plumber.

How does it work?
A gas flow detector determines whether a blockage exists by applying a certain pressure or flow rate to the object being measured and then measuring the change in gas flow rate or flow rate. If the flow rate or flow volume is significantly lower than expected, this indicates a blockage problem.
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 testers can effectively identify clogging problems within a product and play an important role in ensuring that the product functions properly.
The difference between the two
While the two devices may look similar, they can work very differently:
Test Purpose:
- Gas tightness testers are designed to find leaks, while gas flow detectors are designed to detect blockages.
How it works:
- Gas tightness testers focus on pressure changes and gas flow detectors focus on flow changes.
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:
Worried about air and fluid leaks? Go for the airtightness tester.
Worried about a blockage that won't go through? Choose a gas flow detector.
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
Gas tightness testers and gas flow detectors are like the right and left hands of quality control. One ensures no leakage and the other ensures smooth flow. It is with these sophisticated instruments that we can produce safer and more reliable products.
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.
