Review on Cole Parmer Pressure Process Connection Column Test, Measure & Inspect for Pressure & Vacuum by David Lesperance

Before ordering I asked about the true nature of this sensor. "The image shows 0-30 inches of water. Answer: This pressure gauge has a range of 0 to 10 inches of water column. By Cole-Parmer January 18, 2016 However, the answer is not true. is that IT IS NOT IN WATER! IT IS PSI! I matched this to my pressure gauge and slowly added air with my tiny hand pump since inches of water are a much lower reading than psi. The display didn't move. I added air until it moved, I stopped when it was in the middle of the gauge and looked at my gauge, it showed 5psi and 5 on the gauge.
