JACO ElitePro Tire Pressure Gauge - 100 PSI

Clearly, a quality product ! Rubber Gauge cover will protect from serious abuse, except for a direct hit to the glass. Air bleeder valve is handy to fine tune the pressure down to the exact amount desired. I have found this configuration is the most useful in all situations, way better than the pencil style or gas station style gauges.

Nice tire gauge. I bought this for my son to encourage him to stay on top of his car's tire pressure and it seems to be working for him.

eExcellent tire pressure gauge. Accurate, easy to use and very durable. I have purchased several that I have provided to all of the family to keep in their cars.

This is a review of the JACO ElitePro Tire Pressure Gauge -100 PSI. The review is limited by the fact that I only tested a single gauge- the one that I received. I have no connection to JACO and paid the normal price for the gauge when it was on sale.There are many pressure gauge reviews and comparisons on the web and here on Amazon. The web comparisons invariably boil down to differences in features, but never measurements of accuracy. But isn’t accuracy the most important attribute of a pressure gauge? I read comments such as “it’s not accurate.” Well, how do you know? Some will claim that “it’s very accurate.” Again, how do you know? Did you measure it with a master gauge? Some claim that it matches their current gauge and therefore must be accurate. There is some slight reasoning in this, but not a lot. Some claim it matches the reading they got at the tire center. What gauge does the tire center use? Some centers use cheap pencil gauges. Do they calibrate their gauges with a $5000 master gauge? When was the last time that they had their gauge calibrated. Who did the calibration? How many times has it been dropped since then?Consistency and repeatability are admirable qualities in a gauge, but they are not the same as accuracy. A gauge may consistently read the same wrong pressure over and over again.The resolutions or divisions on the dial face or the fact that a digital gauge reads to 0.1 psi has nothing to do with the accuracy. If they painted the dial face with 100 divisions between each pound, would that make it more accurate? Of course not! (Generally, however, the dial face is marked at half the resolution of the gauge, so a gauge accurate to 1 psi would get dial marking at every 1/2 psi.)ASME certification is fantastic, but only if it’s clear what grade or calibration the gauge attained. You can read more about ASME grades at “ASME Pressure Gauge Accuracy Grades at Instrumart”.Some state that digital gauges are usually more accurate than dial gauges. Surprisingly, this one is true! You can learn more about this at both “Analog vs Digital Pressure Gauges at Ralston Instruments” and at “Why digital at cecomp”.Now let’s discuss the JACO ElitePro. Generally I would choose a 0-60 PSI gauge for greater accuracy, but I purchased this one to supplement my Longacre 52-53008 which is my primary gauge. I needed something which reads beyond 60 psi to measure my donut spare tire. A gauge is most accurate in the middle, so choose one whose middle falls into the pressures that you expect to read. I don’t own a master gauge either, so I used my Longacre as the reference. The JACO is claimed to be accurate within 1.5% in it’s middle range ( that’s +/- 1.1 psi at 75 psi, +/- 3/4 psi at 50 psi, and +/- 0.4 psi at 25 psi) One article said to use a gauge with 4 times the accuracy of the gauge you are calibrating or testing. The Longacre fits the bill nicely at a claimed accuracy of 0.2 psi. It’s new. I’ve never dropped it and it comes in a foam lined protective case. It matches my 4 TPMS readings +/- 1 pound, though the most accurate TPMS monitors are said to be accurate within +/- 2 lbs.My first experience with the JACO was not good. User error perhaps. Since then I formally measured it against my reference. Reference pressures on the left. JACO ElitePro on the right.Reference_____ ElitePro55 psi________ 55 1/2 psi40 psi________ 40 psi38 psi________ 40 psi36 psi________ 37 psi34 psi________ 35 psi32 psi________ 33 psi30 psi________ 31 1/2 psi28 psi________ 29 1/2 psi26 psi________ 27 psi24 psi________ 24 1/2 psiThe ElitePro differed at most only 2 pounds from the reference, so I think that it is reasonably good and measured fairly close to its rating for an inexpensive 0-100 gauge, though a 0-60 psi gauge with the same 1.5% accuracy would be more accurate. I doubt that any other analog gauge at this same price range would have significantly greater accuracy unless you just happened to get the cream of the crop off of the production line. Gauges lose accuracy over time and things that accelerate this process (especially for analog gauges) include shock, vibration, temperature fluctuations/extremes, exceeding the recommended pressure limit, dust, corrosion, etc. Store it indoors if possible.

Was shipped and delivered promptly. The hold pressure reading so you don't have to try to read it when you're in one of those awkward positions or in low light is a real plus. I'm sold on it.

Works good!!

This is the highest quality tire pressure gauge I have ever owned. It works great. Much easier to use and much more accurate than any others I have tried.

Greatly appreciate great 👍 👌 🙏
