[Shop-talk] Tire Pressure gauges

[eric at megageek.com]

OK, here is my most 'anal' post to date...

I've been trying to figure out how to get an *ACCURATE* tire pressure 
gauge.  But I have no idea how to check or calibrate them.

Here is the story, I have to work on tanks that need to be within about a 
PSI or two (range is from about 15PSI to about 50PSI).  Many gauges give 
different readings.

So, without spending a fortune (but I am willing to spend a fair amount), 
where can I get a good one?  One attached to an air fill nozzle would be 
ideal.


Thanks.
