Does anyone know of an affordable test kit that does not rely on coloured results. I am shade blind which is quite confusing when using the tab tests. What is even more confusing is that the two different tab test strips I have keep telling me the opposite results. One says my ph is too high and the other is saying its too low!
I give up - someone please point me in the direction of a test kit that tells me in numbers or just plain english. Even Japanese would do - I could always translate from the phrase book. The colours dont work for me at all.
