Accurate Air Pressure Gauges

[dragonle87]

I dont mind 1psi off, i'm getting tired of dial & pencil gauges that's off 5-10psi


Any suggestions?

 

[rlitman]

Get a digital. It'll still be off, but you won't know any better.

I heard LongAcre Racing makes some nice ones.

 

[dragonle87]

i could care less if it wasn't for TPMS

I bought an Intercomp tire pressure guage from tirerack.com. Seems accurate. And I can read it without my glasses.

All Accu-Gage ® 1-1/2 ", 2" and 2-1/2 " dial tire gauges are ANSI Commerical Grade B gauges (meets ANSI B40.1 Grade B specifications), which is the best quality gauge typically used for tire pressure applications. These tire gauges use a fully geared, solid brass precision movement with bronze bourdon tube. Unlike piston-plunger- type gauges, the bourdon tube movement is not affected by changes in temperature, humidity, altitude or air stream contaminants. The mechanical accuracy rating is ± 2% from 25% to 75% of scale and ± 3% below 25% and above 75%. A 15 psi tire gauge is accurate to ± 0.5 psi from 4 psi to 11 psi and is calibrated to ± 0.25 psi at 7.5 psi. A 30 psi tire gauge is accurate to ± 0.6 psi from 8 psi to 22 psi and is calibrated to ± 0.5 psi at 15 psi. A 60 psi tire gauge is accurate to +/- 1.2 psi from 15 to 45 psi and is calibrated to ± 1 psi at 30 psi. A 100 psi tire gauge is accurate to ± 2 psi from 25 to 75 psi and is calibrated to ± 1.5 psi at 50 psi. A 160 psi tire gauge is accurate to ± 3.2 psi from 40 - 120 and is calibrated to ± 2 psi at 80 psi.

A random $15-20 electronic gauge is almost your best bet for general accuracy, unless you're spending high dollars and frequent calibration for an industrial or high end race gauge.

Accu-Gage, Moroso’s 98560, Intercomp, Accutire are good brands.

Funny thing is all my cheap ones are accurate too.

you might be surprised by how accurate those pencil gauges are...

i've been very happy with my $20 joe's glow-in-the-dark gauges

I heard LongAcre Racing makes some nice ones.

I have a long acre gauge and love it.

They have some good re-furbs on the there too. I've had mine now for about two years and have had no issues. They still come with standard warranty.

I have a Matco dial tire inflator w/ gauge, the big one, and its pretty accurate, i like it. It's about 80 something bucks but its a pretty good tool.

 

[jam022316]

Bought this at autozone for $10. Works great in my opinion.

[briggsguy17]

Here's one that has a 1% margin of accuracy. Anything under 100 psi is going to be plus or minus less than 1 psi and comes with certificate of accuracy! Made in USA too.

I have several of these from Best Rest - a motorcycle accessory place. US made, accurate and a bargain, especially now that they're on sale for a measly $15.

I like that one for the fact that you leave it on while airing up the tire so you can watch the PSI, rather than having to stop and check it. That would be very nice for all the times I go off-roading and have to deflate/inflate tires.

US made too, huh? I just might have to pick one of those up!

 

[shampoop]

I've never used a pencil gauge that was even 2 psi off. I would bet that ANY pencil gauge you can buy will be under +-2PSI with most being +-1 or less. Every pencil one I've used has been off by maybe 1 psi at most.

Sounds like maybe you're using it incorrectly?

 

[DrkMtnDew]

Due to the fact that I was dealing with TPMS, I picked up a SO gauge. Very accurate.

EDIT: I also got it waaay cheaper than listed. Wouldn't of paid $100.

 

[mattwgrizwald]

bus garage has one of these and i found my gauge to be 4 psi off

I think the price is around $200.00

looks like a guy could make a checking station fairly easy if he wanted to. maybe i'll try one...

I assembled one with five gauges on it. Rather an easy task, you don't need a fancy anodized block of aluminum. Works with just steel or brass pipe.

It's called an averaging gauge.
I find the spread on say 5 random screw in tank gauges is about 14 lbs at 175. Or in real numbers, with 175 input the gauges are at 180,177,176,175,170,164.
With the clustering near the correct number.
That's five brand new, out of the box, matching gauges.


I use it to test screw in air gauges, but have a screw in tank schrader valve and they are off more than pencil gauges.

I only 'need' tire gauges to be within 2-3% of accurate, since keeping them consistent with the opposite tire is more important than precise settings.

Tire gauges go 'off' by themselves. They also vary by temperature. Not just the air pressure varying, but the gauge itself will read higher or lower based on ambient temperature.

Tires that are hot, just off the freeway, can easily be ten pounds higher than cold tires in a freezing drive way.
So you never get them quite right, best is consistent within safety margins.

I don't have a picture, and it's about 34 degrees in the shop so I won't be getting one.

I have this Blue-Point one and love it.It seems very accurate and the dial is nice and large with a rubber case for good grip,Plus you get a nice blow molded case.

Thanks for posting this - this was exactly what I was looking for (gotta love all the helpful folks and useful info here on GJ )
