Where to buy regulator tester for Kalibrgun?

I do not think the huma tester will work for oem regulator , It did not in cricket 1 , however if you have a huma or edgun reg tester , you can make a adapter out of delron or alum to get it to work , I converted my regto huma as I own many pcp guns and most use huma regs so I like to be able set , test and rebuild my regs from time to time ,
