    Pressure Gauge tested

    Closed the pool and took the pressure gauge to work and had a lab. check it out. Plotted the results 10psi=9.9, 20psi=19.6, 40psi=38.5. Pretty cool tracable to NIST, measurement equipment .25% accuracy.

    It was given to me. Liquid filled with snubber installed and goes to minus 30. It was explained to me that there is no stop at zero so sudden changes don't damage needle movement.
