Review on Joes Racing 32307 Pressure Gauge by Sean Ceo

As with other people's reviews, my gauge is off 4psi in the middle of the range where it should be most accurate. The gauge reads 35psi but three other brand new gauges indicate 39 psi This is approximately -11% error from actual pressure The lowest ANSI Class D standard is 4% difference or 1.4 psi error at a stated pressure of 35 psi at mid-range. A gauge that is 11% off center of range is bad.The gauge is well designed and easy to use.I could keep using it if I wanted to mentally add 4psi to the displayed pressure but I'd rather have one use accurate meter, and requires no mental addition or subtraction to get a good reading.
