Question Cracking Pressure Scubapro g260 and Atomic Z2

[Simpel]

Hi there,

I will be getting a U-tube manometer in the next few days
This one

7102-7103

für die Differenzdruck-Messung500-0-500 Pa oder 1000-0-1000 PaDoppelskala mbar und PaNullpunkt mittig - für positive und negative Drückezwei rote Markierungsreiter markieren den Min- oder Max-Wertbesonders preiswert

What are normal cracking pressure values for the regulators?
I have Atomic Z2 and Scubapro G260

Thank you

The G260 should be between 1.0" and 1.2", while the Z2 should be between 1.0" and 1.4".

Something that reads between 0 and 5 milibars should do nicely.

Thank you

I would recommend a Magnehelic instead.

G260:



Number 8, the "note" you may please ignore or you will chase your tail in circles like a puppy dog.

Hey

thanks for the info
I'm getting the U tube as a free gift and just want to play with it

Fill it with vodka rather than water. The decreased surface tension will improve the responsiveness as your lungs quiver cracking the valve.

I have also received measuring fluid with a density of 1
I will test it with that first

but i love practical tips

Need to add an additional note... If out of limits, suck hard, refill and repeat

Good point. Vodka has a specific gravity somewhere around 0.917-0.94.
So you'd have to adjust your results by 5%.
Measure with a laser; mark with a Sharpie; cut with an axe.
