Review on 📏 MLTOOLS Professional Digital Tire Gauge Air Inflator 68201: Accurate and Efficient Pressure Measurement by Emanuel Frison

Revainrating 4 out of 5

TO UPDATE! CALIBRATE! it is very nicely put together. But it's BROKEN! I fixed it anyway.

UPDATE. On January 15, the gas generator's pressure gauge broke off, rendering it unusable. I had to go to North Carolina for a long time, so I only got back there now, in April. The design flaw is that the sensor's dial is mounted on a 2-inch plastic rod that goes into the grip. Even though it looks like it's a solid body, it's not. There is a 1/16 inch gap between this fragile shaft and the main body of the grip. I managed to lean on it or something and the dial fell out! So I couldn't return it. Secure it with a regular soda straw and some black RTV caulk. I stuck the straw down the stem as far as it would go. I cut the straw about 1/2 inch longer so it protrudes from the stem and connects to the rest of the tube inside the body. I ran some RVT around the straw at the break point to hold the straw in place and the RTV to seal the mating surface. The straw prevents the sealant from penetrating and contaminating the work piece. I then applied a good coat of sealant around the stem about 1/2 inch down from the dial so that when I inserted the stem into the grip, the RTV "glued" the stem to the grip because it was the wrong one gap filled. it hardens within 48 hours and works perfectly again. I find it better than the original in the sense that the stem is now firmly attached to the handle. Sounds complicated, but if yours breaks, you'll see how it all works. . UPDATE: As you know, it's been a terrible winter so I haven't used it too much. A few days ago I was going to ride the bike so I wanted to check the pressure. I hooked it up to the front wheel and got the reading. from 2.7psi? I checked with other gauges and got 38.5psi. Why the difference? I thought it was frozen and destroyed by the sub-zero temperatures it's been through. That's when I noticed it had a red on/off/CALIBRATE button. It came with no instructions so I learned how it worked. ng calibrated to ambient temperature and showed 38.5psi! Now I long press the red button every time I use it and every time it fits my digital perfectly. CALIBRATE! So that the numbers don't get stupid. Indoors, I used it to check the front wheel of a motorcycle (yes, my mom left me in the cafeteria for a while). I got a reading from this of 38psi which was the dead center of the old trusty dial gauge reading 39psi and the digital Accutire reading 37psi. I've tried all the cheap air pumps and they never grip the threads on the Schrader valve well enough to do it with one hand. This one is REALLY good at gripping and sealing, leaving your hand free, and easy to deflate (push halfway in) and inflate (push all the way in). Thumb alignment on the wrist is much more comfortable than pistol grips, and the caliber numbers are large and easy to read. Durable quality construction with a textured grip. This gives me a good read of my GL1800 rear tire hidden under the panniers. In the cold it seemed to read about 2 pounds, as did my other gauges, but it was consistent, which is the most important part of usage (you can easily double-check if you need to). I spent less on this than all the cheap three or four I've bought over the years when you add them all up, so if it holds up - good news. Yes, I agreed with my wife, I should have bought a "good one" first (so I can put my front wheel in the canteen, I suppose).

Pros
  • Great price
Cons
  • Big and bulky
