Electronic/Digital Magnehelic Gauge for testing Scuba Regulators

[buddhasummer]

I know this is an old thread, but being in the market for a Magnehelic gauge I came across this today:

Digital Differential Pressure Gauge

This gauge measures Gauge/Differential Pressure from –55 H2O to 55 H2O with 0.01 increments. It will assist the technician to set up effortlessly the 2nd stage inhalation effort. It features 11 selectable units of common measures - including inches of water -. Additional features include Data...

Not sure how well this works.

Ask @Mike1967 he recently bought one.

How you doing Mike?

I know this an old thread, but unless you're rebuilding regs for hire, why the differential pressure gauge? Set the cracking pressure just short of free flow. The "spec" allows for minor manufacturing variations, why settle for the worst case?

With regs with two points of adjustment i.e micro adjuster you can set lever just short of free flow but still have a reg that's cracking at over 2". For those regs I like to check cracking pressure. I've had G260s out of the box cracking at 2.8", they breathe like dogs. With a single point adjustment reg eg a G250 as you largely get what you get once lever is set I often don't bother checking if they are for me.

I'm no reg expert. YMMV.

i have one, it is OK, but for some reasons, i prefer the analog one, easier to read the peak , the digital one, too many values to remenber which one was the highest, unless you press the HOLD button.​

Hey mate I'm going good thanks, hope all is well in the west?

Yes it seemed to work well but I've only used it once and I've never used anything else to compare it to lol

I'll Skype ya for a catch up

I'm not a highly skilled user, but I have both.

I do not like the digital model for the same reason I don't like digital watches. You have to read digits, decode and interpret, and retain the data. That is a more mental-intensive attention drain than an analog representation poses.

I can interpret the analog "picture" at a glance and it registers. It also shows me how "close" or "far" the needle is from a desired value. ex: clock time big hand is on "8" I know I have 20 minutes before my next task; digital I have to stop and read "40" and do math (kinda).

Trying to catch the point where a reg cracks and not overshoot if the suction pressure continues to go up, in that fraction of a second, is just hard for me to do on digital. I can see the IP needle wiggle out of the peripheral and make a mental cursor on the face of the mag then know where it was.

I have both types and prefer the analog unit.

I don’t bother with either

OMG, Lex! You risk losing your Regulator Geek membership card with a statement like that!

Oh crap, I put the digital one in my Amazon cart, does that get me on probation at least?
