ElitePro - 100 PSI

This is an excellent tire gage easy to use, easy to read as well. I definitely recommend this product. It is accurate and well made. I would buy again.

The JACO Elite Pro tire pressure gauge appears to be just as it’s described. I suspect it will work for generations - tough, simple, well built. Easy to use, and I like the bleed button right next to where you’re holding the nozzle on the tire - so if you over- fill, you don’t even need to move your hand. Just press the button with your thumb until the pressure goes down to where you want it. Good stuff.

UPDATE: After a couple of years of light use my gauge malfunctioned. One day it would no longer zero and was off by 7-8 PSI. The good news is this: the "lifetime warranty" was honored and a replacement gauge was sent promptly. So, it's still a five star product based on the problem response. ==================================================================== This tire gauge is easy to seat on the schrader valve and easy to read whether on the valve or after you remove it.. The pressure reading "hold" function works well and the ability to use the release button to bleed excess pressure and instantly read the new pressure is very nice. Accurate adjustments to an over inflated tire are easy. The ribbed, protective shield is a nice extra both for ergonomics and protection of the gauge housing. I've used a fixed shaft Milton with a round gauge head for a number of years (like 25 years maybe). It also has a reading hold feature but no bleed down function. I've liked it very well for a long, long time but the calibration is less than perfect after so many years of use and the reading hold function doesn't always work now. I also have a digital gauge that fits motorcycle tire stems and an old school tire inflation type of gauge also from Milton. The Milton inflator has also been a really good tool but it's old now and is always 1.5-2 pounds low these days. Comparing what I know about all of my other gauges, the JACO seems to be very accurate on pressure. It's certainly easy to use and I'm very happy with the gauge. I hope it lasts as long as the Miltons.

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_____ ElitePro 55 psi________ 55 1/2 psi 40 psi________ 40 psi 38 psi________ 40 psi 36 psi________ 37 psi 34 psi________ 35 psi 32 psi________ 33 psi 30 psi________ 31 1/2 psi 28 psi________ 29 1/2 psi 26 psi________ 27 psi 24 psi________ 24 1/2 psi The 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.

This Jaco elite pro pressure gauge works great for what I ordered it for. Perfect length to reach all 4 rear tires on my motorhome/rv. Would absolutely recommend this pressure gauge as it does not require batteries and can be stored and work as intended months later!

Seems like a solid unit, I have others but this one claims to be accurate, checked it against my cheap ones and this was definitely different

Works great

Update: Vendor has given a full refund with apology. Good seller, just needs to QC the products better. Would not hold pressure out of the box. Cleaned the check valve as described in the instructions. Still no go. The pressure release valve seat in the main brass tube was incorrectly machined, causing a leak at the pressure release valve. Had to unscrew, re-assemble with epoxy to fill a leaky void. Next leak: the "O" ring that seals the check valve assembly (the internal seal that is attached to the hose assembly) was injured during manufacture. Had to replace the "O" ring. Finally holds the pressure reading. Should have just sent it back, but I like to find out what is wrong. This unit obviously did not go through any quality control. I question the accuracy now, if this basic function was missed. Very low quality assembly. I love buying something and having to fix it. I will not buy another one. BTW, cheap CH import marked up for our market. These guages are on a number of different brands. Pick another type. The guage itself "seems" ok, just not the other assembly screwed on to the guage.

Excellent pressure guage , quick , easy to read gauge and accurate. I do summer / winter tire & wheel swaps on five xars twice a year and this is worth the $$ .

Enfin une jauge precise !

I bough this JACO gauge as the brand is highly recomended for accuracy. I've had various cheaper brands previouisly but they are so inaccurate by upto 4 PSI, I decided to splash out on this one. Unfortunatly despite being accurate, the valve end fell apart on it's 2nd use, reassembling didn't help it kept on falling apart. No shock then, that I have since returned the item. So very dissapointing.

El articulo es de muy buena calidad y precision.
