Review on 🔧 Accurate and Convenient: Victor 22-5-60108-8 Dial Tire Gauge with Flexible Hose by Eric Jones

When this arrived it was about 7psi (low), after a bit of internet searching I found someone on YouTube showing how they are calibrated. After unscrewing the pressure gauge from the fittings, the front frame is carefully pulled together, after which the mechanics can be unscrewed from the rear case. There is a U-link on the movement that can be fine tuned (as in microns) to adjust the reading and trial and error to dial it. I got about 0.5psi from all my other sensors and TPMS. The test reader tool I have is good enough for my needs.
