I would not use a high-range pH kit, I would use a general one. Don't know what this may mean, but as the pH starts out around 6.4 I wuld use a general range kit.
Have you let a container of the RO water stand without anything in it, just a glass full of the water,and tested it the next day to see if the pH changes?
He should be using both pH tests because if one maxes out, then you are supposed to use the results from the other. The standard test range is from 6.0-7.6 and the high range test is from 7.4-8.8. API breaks it down like this to be more accurate.
