Stay away from this product.

It is improper to test a vacuum gauge in this manner. You must have volume to test vacuum. Because the vacuum gauge checks for space between molecules. If you test this gauge with a tank hooked to vacuum to provide volume you will find the gauge will pass a decay test.

Man its not even problem this is so normal for this tiny amount of space that you have, who discovered this procedure to test micron gauge like this by (connecting with ball valve or core removal tool) this is big mistake.
You can know if the micron gauge works with no leaks or problem by check the lower value that will reach when its connected to vacuum pump directly, and test it on hvac system or recovery tank (to make sure that there is enough amount of volume)

I would be careful with cheap core extractors. They are notorious for leaking vacuum.

The problem you have it is with the Try to do it with hoses and check the difference.

Maybe u should try to check & clean the filter

I'm not convinced by that Vacuum Meter 🤔🤔

There is included o rings did you tryed them? Oring touch surface also doesnt look smooth.

[SarjanaObeng]

Do you have any other micron gauge device? Have you try that decay test on the other unit?

Same problem here 😢
Generaly élitech has best products in technology but no accecory or part for sell, like me i have élitech emg-20v manifold that has digital screen and i broke the screen and no screen available for sell i contact élitech in US and UK and china and they said no accessory available for sell so i steck with a non working manifold 😢
If any one has solution tell me

There is nothing wrong with that vacuum gauge homie.
