As above.

Surely in 2014 someone has managed to stick the right threads on a digital gauge and be able to flog it for significantly less than 216

Do a search for a Keller Eco 1. About 100 and screws straight into an ap decanting hose

The 30bar ones are around that price but the 300bar O2 ones are €200+

They are a lot more resonably priced alright. They are 1/4 NPT is that a standard fitting or will I need adaptors? I would like to use it on a Undersea blending whip and down wind of the filter stack and non return valve of an Undersea Personal Filter

Woz, thanks for the info, what is the Range that the ECO 1 reads?

Thanks

Where I want to fit a gauge to is here (BTW in some of the pictures it looks battered but that is just the light).

My question is whether the 1/4 NPT thread fit the above thread? Is there anyway to tell what the above thread is? I cant find a spec sheet online for the filter. Is 1/4 NPT the same thread as anything else I am likely to already have so I can check?

Okay I have been informed by SAP that the thread on the filter is a G1/4 or 1/4BSP. The gauge on N@90 is 1/4 NPT.

I cant get through to SAP to find out if they sell an adaptor for female 1/4 NPT to male G1/4.

Surely someone has done this before?

If it's in the undersea catalogue then Mike at SAP should be able to get if for you.

Mike has got some of the adaptors in since Thursday. I am waiting for a local to get back to me on a price but will probably go for the N@90 &adaptor unless the local lad can do something decent

Ended up going for the N@90 guage in the end. Rather than add it where I was originally planning on the filter I made up a block and put it on that. That way it can be used for any purpose: adding O2, filtering air, decanting etc etc
