I improvised when I had to do this a few years back, used a tire inflater with a pressure gauge, taped it up with vulc to seal against the bottle.. Tapped the trigger gently a few times and held it in place a few minutes to make sure pressure didn't drop. Could easily have zip-tied it to the bottle to do ocular inspecition for leaks..
