Incorrect Gauge Reading on Air Compressor

[Haani]

Hi Guys!

So I bought a 300L/min Camel Air compressor from Dragon Mart and while using it this weekend, I noticed that the inflating gauge shows the incorrect tire pressure. Many at times half of what the actual tire pressure is!

Are there any ways to rectify this? Or should I go back to the shop I got it from and ask them to replace it?

Cheers!

Hi Haani,

I haven't seen so far any accurate gauge on those compressors, mine is off by around 15 Psi, I just know how much is it off and inflate a bit more than I need, for example if I want to set my tire to 35 Psi I just inflate it to 38 and set it right with a proper gauge, but never depend on those Chinese gauges to set your tire,

I don't think it makes sense returning it, hope that helps!

The thing with my gauge is that it doesn't seem to be off by a fixed value. It keeps fluctuating and I can't seem to find a pattern to it. Sometime the gauge doesnt even return to 0 or a certain number when not connected to a tire

I would recommend that you ignore the gauge on the air-compressor, and use time as your indicator. For example it takes ~ 2 minutes 40 seconds per tire to go from 10 PSI to 40 on mine.
After a few tests you'll figure it out for yours.

hello everybody .. the gauge of the chinese air compressors does not read accurately while the compressor is on. you need to switch off the compressor and read the gauge.

That's great advice. Thanks everyone!
