How many mm to a HG?
as a general guide, i am 7.8bp, and I would pump to 170 and evetually 190 over 10-15 minutes.
this resulted in ovetraining, I now pump to about 130 /140 for a solid 20 min session no breaks, with much better results in EQ.
HG stands for mercury, the element associated with this rating. The mm stands for millimeters of mercury. The difference between your nonpumped and pumped length should give you the approximate pressure used.
anybody knows where 5hg is located on the bathmate Hercules how many millimeters is it. theres no gauge for the bathmate hercules to tell me. did anybody measure 5hg in mm.
Secondly, the design of the bellows (the rubber part of the Bathmate) does not allow you to exceed the negative pressure threshold of 0.4 bar. Compare this to the FDA (Food and Drug Administration in the United States) which states that any device that uses more than 0.56 bar of negative pressure in Penis Pumps must go through FDA testing and approval before it is allowed to be sold in the United States. Similar rules equally apply in Europe and all around the world.
After pressure testing the ‘Bathmate® Hydromax® X30 Hydropump’ twice it reached an average of -0.5 Bar or -14.76 inHg.
Hercules and Goliath at 0.33 bar (9.74 in Hg)
X30 and X40 at 0.55 bar (16.24 in Hg)
Xtreme X30 and Xtreme X40 at 0.65 bar (19.19 in Hg)
No No NO, please explain how this is possible. You plain and simply can not measure pressure this way. You can measure expansion but you have absolutely no clue of how much vacuum is created. Not all penis's expand the same under pressure so how can you say you have 5 mm of mercury, think hard but don't try and answer, the shovel is broken.
So how much negative pressure is 5 MM?
