Re: Tire Pressure Gauges

["Doss Donaho" <ddonaho@xxxxxx>]

I recently collected all my gauges and did a test.
I had several pencil gauges, several electronic freebies from marlboro, and
one good $30 gauge.
I sat beside my tractor and tested all of them to see how they compared.
I started at about 10 psi and went up to almost 40 psi. ( it is a tractor
after all)
The electronic and expensive gauges were always with 1 psi of each other.
As near as I can tell so were the cheap pencil ones.  The only problem with
them was that they were harder to read and I wasn't sure exactly what number
they were telling me.
After a while I could estimate with the all the pencil gauges within 1 psi
of the $30 gauge.
My original idea was to toss the pencil gauges and distribute the electronic
guages to the varoious places I needed them.
I wanted to be sure the electronic gauges were acurate.
I ended up keeping all the pencil gauges and have much more confidence in
them now.
I love my $30 gauge and would buy it again, but I don't feel so bad about
all those years that $30 for an air gauge was just to much.
YMMV
