Need an accurate tire pressure gauge

[rogerkathy]

Ok, I have two different air pressure gauges I use to check my tire pressure. They do not agree with each other. In fact, both seem to give different readings when compared to themselves. One I use (older fashioned one that has a plastic stem that pops out with the scale showing psi even will go to a specific psi then slowly keep extending. The other has a round gauge and a release pressure button. I am looking for gauge recommendations that have ACCURATE AND CONSISTENT psi measurements. Suggestions?

I have a digital gauge from Groit's Garage that works well and adapted a bicycle pump hose with valve stem locking chuck. 90 deg and 45 deg valve stem extensions help as do self sealing metal valve stem caps that stay on the valve stem permanently.

This is the one I have and I find it is Accurate

Designed for duals, very accurate with 1 pound increments

Ordered the following:

1x EliteProPlus™ Tire Pressure Gauge with Interchangeable Air Chucks - 160 PSI for $30.95 each (minus a $4 discount)

Looks like it's made in America and has 100% warranty (I hope). Haven't had a chance to try it out yet but it seems really sturdy and seems to have brass fittings that are good quality. Will try it out this week.

Tried the new tire gauge. Feels great, is sturdy, and well made. Appears to be accurate but haven't compared it with others (which could be inaccurate like my cheaper ones). Just need to go by faith. So far I would reccomend it.

By chance I had ordered the same one thru Amazon. About the same price as yours with discount. I also have TST507 TPMS system on the trailer. I will compare the readings from both and report back.

To make sure it is accurate, take it to the local tire shop and they can test it. I had two supposedly "accurate" gauges which really weren't (off by up to 15%). I finally got one that is accurate, https://smile.amazon.com/dp/B00080QH...&pd_rd_w=J0WFD
I've had this tested at two tire stores and both say it is very accurate.

Unless the manufacturer is calibrating the gauge before it is shipped, accuracy is a crap shoot. You have no way of knowing without calibration - and calibration costs money. Comparing a gauge against another gauge is the poor man's calibration - you don't know if both gauges are out of wack. The more comparisons you do, the more likely you will know if your gauge is off or not.

Precision is something different. Precision is how small an increment you can measure, accuracy is how close the measurement is to the true value. Unfortunately, digital electronics can give a false sense of both precision and accuracy. When your gauge reads to a tenth of a PSI, you think you have both precision and accuracy. But that doesn't mean the sensor has either precision or accuracy - the processor could easily be making up that tenth of a PSI digit when the sensor can only measure to +/-2 PSI. Consumer voltmeters and multimeters commonly have this issue, too.
