How accurate are gauges on guns?

[Firewalker]

Ooooooh, sorry. My recommendation is to de gas the gun, see if the needle is off of the stop pin when degassed. I've taken note of where it lies and just increased accordingly . If the guage is for general reference only it's no biggy. When tuning I follow all other signs more than a pressure guage number.

Im sorry but this is why there is such a big window for the 0 PSI indicator, these spiral gauges are notoriously inaccurate at low pressures, they are much better at high pressures.

NOTE: I said my gauges were within 100 BAR of each other.WRONG! Within 100-200 PSI is what I meant. Changed it in my 1st response.

Sadly, that's about what you can expect from high volume manufacturing.

I am new to pcp air guns and air compressors Is there any indication of a gauge on the air gun or the air compressor not reading correctly?

You hit the nail on the head for me. In hindsight I should have worded my question differently. If the gauge is consistently off I'm okay with that as well, That is all I'm worried about! My main concern is the tuning aspect and not blowing myself up!!!!!! For tuning would you suggest just making my adjustments off of my external reg and making notes of where it reads on the gauge itself?

I don’t trust OEM gauges - thus I always underfill

They're just not PRECISION gauges but they do give a close ballpark reading within a couple hundred pounds. It's really not a problem or anything to cause concern.

If you want an accurate guage for your gun, get a Sekhmet. Just make sure you get the latest firmware update. Prior versions had bugs.

No need...

Any vessel max pressure is 1/2 to 1/3 of failure pressure.

I have a couple of the huma test gauges to give me an idea how close the other gauges are.

If you get these be careful which you choose and make sure you have the correct adaptor for what you are using it for. One only goes up to 250 bar the other 400 bar but has a G1/4 thread.

Sorry could not post my pictures

Here is my soon to be replaced Wildcat reg gauge… talk about low resolution, and that’s the reg gauge. Also the replacement I happened to have on hand.

I looked at those things and they are super nice! I am going to get one for sure! Thanks for the advice.

I bought a Sekhmet Digital Transducer Pressure Gauge . I have it mounted on a foster fitting and use it to set my Compressor to the PSI i need to fill any o my guns as a test before i fill a gun .

My CS4 was 35bar under, 8 bar on the E-5K1.
