Review on 🧲 HFS Filled Vacuum Pressure Gauge: Accurate and Reliable Measurements for Precise Applications by Alex Jones

Seems ok but for the two i had (i had to return one in exchange for the other) they don't reset after a while and even if you air through the plugs bleed, it wouldn't matter. The last thing I have seems fine so far, but I'm proceeding with caution. Probably not much more than the relative pressure reading and it would be wise to use more accurate instruments to get better readings, at a higher cost of course.
