Nifty.

If the tire gauge has a brass scale, instead of a plastic one, it's probably the best tire gauge you own. I worked in automotive service, several careers ago, when a Scrader stick was the industry standard. When they changed to plastic internals, accuracy went to shit. Non-conatct thermometers can be useful, but they can also be deceiving. WHERE you point to measure, makes a BIG difference. They generally measure the temperature of the outside surface of whatever they're pointing at. If you try to measure something like coolant temperature, say, inside a thermostat housing, accuracy isn't so good.

There isn't anything at all plastic of the tire gauge I bought at the pawn shop yesterday.I checked it for accuracy this morning against my other newer tire gauges.The old tire gauge seems to me to still be just as accurate as the day it was manufactured. cuhulin
