Digital tire pressure gauge that doesn't s@&k?

[tclark]

without letting any air out

I've seen this mentioned a couple of times; just how much air are you guys losing when checking tire pressure?

I bought the Jaco digital tested best by in the Farm video

The gripe isn't so much the amount of air, it's more about fumbling around trying to get a good seal with air leaking out while you're trying to get a reading. This is why I'm lobbying to have a secure sealed grab prior to getting a reading.

Have a Longacre analog that I picked up almost a year ago.......wish I would have gotten one a long time ago. Its outstanding

I'd just like to find more gauges that have right-angle chucks. The angled or straight-on BS is completely useless for motorcycles. There are a few out there, but not many.

I'd also love to find a better option for a lock-on 90 degree inflator chuck than those nasty cheap garbage tinfoil dammits with the plastic levers. They're an asspain to use in tight quarters, and they wear out after some number of uses.

Just released for your edification. Our buddy Todd at Project Farm does tire gauges.

Just to save everyone the headache, the Jaco digital came out on top by a country mile.

The Merlin inflator with digital gauge from HF also did well.

None of the dial gauges were very good, even the Jaco and Longacre.

I was surprised to see so much variation between samples (he tested two of each), and the wide variations and inaccuracies in the small digital gauges was pretty wild; these are based on pretty much the exact same chip and electronics, but I guess no one bothers to calibrate them?

As ever, his testing process had some... oddities. For example, the deviation in readings at extreme hot and cold temperatures (he tried the gauges at 120 degrees and at -20F.) was given the same weight as more important metrics like accuracy at 40psi at room temperature.

At least he briefly flashes the data on the screen at about 18:45 so you can pause and get a good look at it.

At least we were spared pointless destructive testing...

For many of us, "room temperature" IS -20F and/or 120F... especially those that do not have a climate controlled shop and live in the northern part of the hemisphere where our 4 month long winters are -30F outside, 4 month summers of 100F, and then 4 months of **** in between that some consider "room temperature" ;-)

The Topeak Smart Gauge D2 marketed for bike tires is what I. Use not just for bike tires, but for my car. It barely lets a peep of air out when you press it on to read, and same for when you release it.

You can switch it easily to read both Schraeder and presta valves. It uses button cell batteries that last a long time.

True; this is valuable data. But I was questioning why the extreme temperature readings were weighted equally with the more or less "standard temperature" readings in the final rankings.

Then again, weighting would require some sort of judgement call as to how important these are, which varies a lot between individuals, so I can also see why he just stirred it in.

When i saw the thumbnail by brain practically defaulted to "oh, i see Todd is putting tire chucks in a hydraulic press this week, anyways..."

My Christmas present this year was the JACO ElitePro Digital Tire Gauge. 0-200 psi with accuracy of 0.5%
Color me impressed. Reads in 1/10 psi increments. I fill the tire to about 1 psi above the desired pressure and then use the release valve to lower to the actual number. Performance is outstanding. Price is very reasonable (about $30) and shipping is free.

This is what I have attached one of my compressors

JACO FlowPro Digital Tire Inflator with Pressure Gauge - 200 PSI

Amazon.com

My inner kid got the trusty old gas-station style Milton inflator for the compressor.

Because of this thread, I got the analog Jaco gauge. I think 0-60psi? It's excellent.

I have the Matco DTPLG851. (Cal-Van 85110)
It’s an illuminated digital tire gauge (150 psi max) with two worklights, front tip and side. The tip light works well for taking readings in the dark. It has two magnets, the base and side. Pocket clip. USB-C rechargeable w/ battery meter.

I have a Motion Pro Digital gauge that consistently reads 3 psi above what my two analogue (Motion Pro and Longacre) gauges read. I don't know which are the correct pressures, but I'm guessing the analogue, since they read identically.
