Inaccurate air pressure gauges

[Gump]

I bought that Victor, flexible hose, holds the last pressure reading, mechanical gauge, a couple years ago, and it's either not accurate now, or always was junk. It reads 7-10 psi lower than actual depending on pressure.

Just a word of caution to check them against others. I have two $0.50 pencil types that are old and read correctly.

Me too. That's the most expensive gauge I've ever bought and its junk.

The slime digital I have is within a half pound of a $100 gage my uncle uses on his race car.

I've had my Accu-Gage for 20 years.  Accurate and costs about 20 bucks

Hell my cheap craftsman 19.2 volt air pump even only reads about 1psi low

Longacre.

This one, specifically.

I was checking a small trailer tire when I thought, there's no way it had that little amount of air in it. 10 over in one of those, an already old tire, could be bad.

Makes sense that when I got my bike and tires back from Pauly, I thought my tires were awfully low, but they weren't.

If you are not sending your gauge

off to the Bureau of Standards,

how do you know it is off, or the

ones you are comparing it to is

correct?  Do the ones closest to

the same reading win the prize?

Best two out of 3 and my eye, foot, scale.

Per ISO 9000 standards, you could calibrate a used one against a new one if it comes with a calibration certificate.

Yep. Damn kids with their expensive toys that don't work. My slime has worked for years through multiple bikes and it is dead on.

I had pencil type gauge and it's not that accurate. Now, I'm using the Meiser Accu Gauge with flexible hose.

At work, I found out that my Milton inflator gauge was reading very inconsistently, sometimes right on, others high by a few pounds.  I have gone to using a cheap-o, old school pencil type gauge, and it's always within a pound of what the TPMS sensors read on the cars.  $50 Milton vs. $$5 pencil type.  It's much more convenient to have the gauge in the device that you'll be inflating with, but accuracy is much more important, especially when the pressures read on the dash, and people could see that your gauge is wrong!
