<div dir="ltr">I believe I have the same one as Cliff. I'm going to look into swapping it out for a SCUBA second stage, which I think will be both more sensitive and definitely able to handle a larger off-gasing volume. What I'm wondering about is how to connect something that's intended for a human mouth to Swagelok tubing instead. Any suggestions are welcome!<div><br></div><div>Thanks,<br>Alec</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Oct 15, 2019 at 1:14 AM Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Cliff & Alec,<br>
I have just been playing around with my Parker miniature regulator.<br>
As Alec noted there is quite a bit of pressure difference between the set<br>
pressure & the relieving pressure. I have been turning the pressure up<br>
to 20psi & then turning it down, & it takes a lot of turns to bring the pressure<br>
down again. Ie. 1 full turn to go to 20psi but 2 full turns to drop pressure<br>
back to zero.<br>
I am using a cheaper Aluminium version for experimentation & bought the <br>
0-125 psi range, which In hindsight was a mistake as I am not getting the <br>
sensitivity I need.<br>
What range did you guys buy. I see you can get 0-25 psi.<br>
I am running my thruster full of silicone oil & just a few inches of air in the feeder<br>
tube from the regulator. <br>
