Review on Winters PEM212LF Pressure ±3 2 3 Accuracy by Patrick Reid

I bought 4 of these sensors. One gives the correct pressure, the second is off by about 1psi (read 11 if it's actually 10psi - not a big deal for my application), the third is off by about 4psi (16psi). inches is actually 20psi) and the fourth gauge seemed fine when I checked, but instead of going back to zero it stuck at 8psi and was far from normal. I'm returning the last two. I will not be buying any more Winters gauges.
