The Brewer's Edge Dual Stage Micro Regulator is the first affordable cartridge regulator to feature two chambers instead of one - first, a high pressure chamber for the C02 feed, which feeds through a regulated piston to a lower pressure chamber with a diaphgram regulator on the dispense end. This allows the dispense end of the regulator to be more precise and accurate, as it is not trying to throttle C02 down from 600 PSI to 10 PSI. It also maintains accuracy throughout the life of the C02 cartridge, even as pressure drops in the cartridge when it nears empty, and does not need to be readjusted periodically to maintain a set pressure.
This 0-23 PSI C02 regulator comes with a ball lock gas fitting to fit kegs and mini kegs, and fits 16 gram threaded C02 cartridges out of the box. A 74 gram C02 cartridge adapter is included, and you can also purchase an optional Sodastream® C02 cylinder adapter (our item R44). The pressure range of 0-23 is wide enough to allow both for fine dispensing control and carbonating.
NOTE: This regulator does not include a pictured cartridge, these are sold separately. For C02 only, this regulator will not work with nitrogen or argon gas. Fits all ball lock kegs.

Q: Can you use nitrogen cartridges with this regulator to dispense cold brew?
A: No, it is not designed for the higher pressure of nitrogen.

Q: Can you add gas line to this?
A: Yes. You could attach a gas line to the micro regulator by removing the fitting for the ball lock and replacing it with either a male flair fitting (L38) or the duotight adapter (D63) depending on your system requirements.

Q: Does it have an internal check valve to prevent liquid from entering the regulator?
A: No

Q: Is a 16g cartridge enough to push out a full 2.5 gallon keg?
A: No, you will need 2-3 cartridges to push out a full 2.5 gallon keg. This depends on how carbonated the beer is in the first place, and serving temperature, so your mileage may vary.

Q: Have you tested this to see how long a 16g cartilage will last? For example: 5-6 psi just for dispensing? I understand the results will be subjective. Just would like an idea as single stage are worthless.

Swapping out adapters went poorly for me
It worked right out of the box with 16 g, so great. Went through 16 g cartridges like crazy with a 5 L mini keg, so I switched to 74 g. When I swapped the fitting for 74 g, it worked. Here's the rub - when I went back to 16 g (had some left over that I wanted to get rid of), that's when I had problem. Put in a new sealing gasket (the adapter/fittings have different base diameters that depress the gaskets differently) and somehow the puncture pin of the regulator was WAY too high into the screw hole for 16 g cartridges. I tried and retried like 10 times - every time checking that the gasket was pushed in, I wasn't cross-threading the adapter, and I only tightening light wrench tight (needs a 7/8" wrench). Every single time the puncture pin/hole was like slightly more than halfway into the 16 g screw area. Impossible to thread a cartridge like that.
Way better than other mini regulators
This mini regulator is much better than other regulators. It is easy to dial in the exact PSI you want and it STAYS there. The 74g adapter works great, so much better than 16g. I will order the soda stream adapter now as well.
Quality regulator
This is my second brewer's edge regulator and it is well built and very solid. I've had my other micro edge regulator for a few years now and it's served me well, wanted one with a gauge so I bought this one. The dial does not had markings on top for increase/decrease but not a big deal.
