Used to teach professional installers the difference between water column and psi. The guy almost killed a bunch of people because he couldn't tell the difference. Natural gas is inches of water, not ounces per square inch. My goodness. Must be a public school thing. Great quality, works great and well calibrated compared to the actual water column measurement.
