Digital gauges

[NorthWoodsDiver]

Well I have decided I am going to include a digital gauge into my blending whips, I want to keep it cheap but I also want quality, accuracy, durability, a minimum pressure of 4000 psi, and what I really need is a gauge that doesn't have auto shut off for at least say 15 min.

with those requirements I have narrowed it down to 2 gauges I think, the Ashcroft 0-5000psi gauge and the Dwyer 111 gauge. both are accurate to .25% FS they are from what I have found the best for the price. If someone knows of a better gauge with the same accuracy for cheaper please clue me in.

It took quite a while to find a website that sells these things and I dont really have a site to compare prices with but this place sure has a good selection. Transcat - Product Search

I am including a poll just to spice things up a bit but please do share any additional comments.

NorthEast Scuba Supply Good folks, lots of parts (with photographs), and good prices. I get a lot of knick-knack type pieces from them, and they're very friendly towards this type of activity, which is even more important.

I recently rebuilt my whip (which I use with a BabyBooster) as one of the feed lines had developed a leak that was noticable with helium, although oxygen still worked fine. I used the opportunity to pick up a Dwyer gauge from them to convert the output, post-check valve, to digital for easier PP blending. I then put a small analog gauge on the input side (along with a Whitey needle valve) to make reading source pressure a lot easier... and answer the "why is it taking so long to top a 13 cf bottle?" question.
