I do not think this has been posted here as I looked for it but did not find anything. I called to see what the pressure equivalents were per gater on the penomet and the lady did not really have a good answer. She gave me numbers but when I asked for a unit she did not know. Based on what she gave me it has to be pascals or pa which you can then convert to hg which most other pumps measure.
BLUE 465 —> 3.49mmHg
BLACK 470 —> 3.53
GREY 475 —> 3.56
Those are the only ones I asked for but Im sure the others scale at increments of 5 as well. Does this look accurate? Very minimal increase as you change gaters compared to what you can get from an electronic pump.
