How accurate is the gauge? Spot on? Or +- 1?

I have not done a calibration to establish +/_, however, the fill gauge reading and pressure fill adjustments was also confirmed by my GMC Truck pressure sensor system monitor.

I think it is very accurate according to my experience, but I didn't use other expensive gauge to compare though.

The only thing I have to compare it to is my only other air gauge and it is a very cheap one. So I can only assume that it is accurate.

If it don't move probly not working actually I was not to happy with this gauge , I purchased a different one witch I like a lot better, this one seamed so big and stiff ! Good Luck

No. There's a chrome-colored knurled female tip on the gauge. Make sure it is screwed tight!

I'm not quite sure what you mean by that but the gauge runs from .012 to .053 ins or 0.3 to 1.35 mm. Hope that answers it.

I've found it to be 100% accurate and have never had an issue with it. It worked great right out of the box.

My gauge reads up to 120 PSI. Well worth the money as I patched a nail hole in my 20" truck tire and it has held for over 6 months. Hope this helps!

I didn't have any problem with the gauge. Having never used this product and not being a car guy I was using the gauge, but once the compressor kicked on the needled redlined. So I had to start letting coolant out, while the compressor was engaged, until the needle on the dial dropped back to the proper zone. Some of those responses may have been from people like me who have no experience and just don't know how to work it properly. That being said, I am sure you could buy just a gauge on amazon or your local car supply store.

I am not buying the hype of expensive test kits. I have always used the cheaper kits and have never had any issues. There are instances where you need to be as close as possible to an exact reading but I've found close enough is good enough. Go cheaper in this case.

It seems pretty accurate. However, the latch is not tight on ours..the metal hook seems to large, so if that is an issue with yours that might be the culprit for fluctuating temp.

Like most other pressure gauges that are part of the air compressor,they seem to read high until you turn the compressor off and wait until it "settles".Then the reading is accurate.Just go a few lbs. over,shut it off,wait a bit and look at the gauge.If you over fill,it's just a matter of letting some air out.No big deal.It's a super good compressor.

I don't think that there was a bad batch. You have to set these gauges up a certain way. If I remember correctly the instructions that came with the gauge tells you how to do it. If not you might have to research it online.

its very accurate. had it tested again the gauges at Sam's club tire dept as my son works there.

I've not had any issues with the guages. They seem pretty secure. I've been pleased with it thus far.

I used a short term test like the one from First Alert to validate the readings in my basement and it came out accurate. Make sure that you carefully place the unit because placement can effect the readings. 25 is pretty high but certainly in the range of possible - don't ignore it !

I doubt that it is "accurate" in terms of being calibrated to any significant extent. I just line the up the disk to where I want it and it is very close to my floor pumps reading. I just use it to finish my ride if I get a flat. If I'm within 10 psi I'm happy enough to get home.

After 20psi there are five intervals for each increment of 20psi, so they represent 4psi each. From 0psi to 20psi there are three intervals over a narrower physical distance. That's where the gauge is pretty non-linear--I wouldn't read too much into readings below 20psi.

This pressure gauge gives me the same readings as a high quality bicycle pump with a built in gauge. As far as it's accuracy is concerned, I've not compared it to a master gauge yet for accuracy.
