For a long time I've wanted to get myself a regulator tester so I could test the regulators in my airguns. But trying to get a hold of one has proven not an easy task. Now I do have a lathe and I could build one of my own but I would much rather just buy one if I could find one at a reasonable price. I've know about the Huma regulators for a while and have a couple of them installed in a couple of Edguns I own. Fantastic tiny regulators by the way. Anyway, I discovered they also sell a regulator tester for their regulators, so I bought one. I ordered the thing from Huma's website on 3-1-2018 and it arrived yesterday, 3-19-2018, via the USPS. It was shipped from the Netherlands and just so you know, an adult needs to sign for the package when it arrives. The cost was a grand total of 111.53 euros or $140.97 at the time of the order. If I ordered it today it would be about $136.56, I guess the dollar is doing a little better.
So today I was looking at the tester, and it looks more like something Rolex would use to service their watches, than something to test air gun regulators. It weighs more than it looks like it should and it's built rock solid. The body/chamber has a large oblong hole machined into it, so the chamber isn't meant to hold any air, the chamber only serves as a way to secure the regulator, which itself is the actual air chamber. There is an oring at the top of the chamber and another in the screw on cap, these orings press against the top and bottom of the regulator body and seal it. With this design there is almost no wasted air when you pull the regulator out. There's a large easy to turn screw knob, to release the air on the regulated side of the regulator, and a large easy to read liquid filled air gauge.
I pulled the regulator out of my Edgun Leshiy and installed it into the tester. Hooked the tester to my regulated air tank set at 190 bar, and the tester works perfect, no air leaking anywhere and when I open and close the air release valve, the air escapes and the regulator quickly replaces it at the set regulator pressure. I have the Leshiy regulator set at 110 bar, according to the paper indicator on the regulator. The tester shows the regulator pressure is set at 112 bar with no creep.I then pulled the regulator out of my Edgun R5 which I set to 123 bar according to the regulator tester, but according to the paper indicator on the regulator it should be at 130 bar. So I've learned that the paper indicator on the regulator isn't exactly accurate.
As far as using this tester with regulators other than Huma's, I don't know if they would work. I doesn't appear that the stock Edgun regulators will work with this tester.
This is a very nice and not too expensive tool to have if you want to see how your Huma brand regulators are working and at what pressure they are set at.
