Max IP for DS4 ??

cys · 2nd July 2007, 17:52

I have the info. They cost about $3 each. I bought several, but haven't tried one out yet. Since I am a secondary source for this information (I got the info off of the apparently now defunct (non-Jetsam) KISS yahoo list), I don't want to post it, but you can pm me for details if interested.

hello sepp,

seems there must be different versions around of the DS4
I tried different, they all blocked at +12.5 bar

Don't need to fix the IP on my inspo

but I have seen nearly 1 bar difference between two IP gauges on the same reg.

The max mine will do and be stable is around 12.5 bar; note however that they are also stable down to around 4.5 bar! The latter is extremely useful for eCCRs with depth compensation if you want a LOWER flow rate through a solenoid (and/or manual add) valve.

Are you sure you don't need to lower your IP for the O2 on the Inspo ?

Yes, the difference that people are posting about getting above 12.5 bar is (IMHO) due to the inaccuracy of the IP gauge. Verify with another IP gauge of a different brand...

Repeating the second question asked......Has anyone previously checked out and documented the DS4 IP Linearity with decreasing tank pressure ??

Also repeating... best data obtained would be with test points read under no-flow conditions, and trapped IP from any previous checks dumped before reducing tank pressure and taking the next IP check reading.
