Do the cheap ones that are a metal probe with a plastic meter work?

Excellent Q I just bought one exactly like that and I have no clue how to use it...I was told they work but I have no experience using it yet.

i have one of those.(similar) actually just used the thing like 10 mins. ago. I never actually checked the accuracy against ph paper or anything, but it seems to work well. you have to let the thing sit in your material for several minutes to get an accurate reading. it may not be a perfect measure, but it sure beats guessing.

Seriously?Orange juice - 4.4 Ph
Apple cider - 4.8
human spit - 5.4
baking soda - 8.5
Hope this helps...

You can make your own test strips by chopping up red cabbage and boiling it for about 20-30 mins, then strain the cabbage, and you can use small amounts of liquid in a glass. Just add a drop or two of the liquid to be tested to the purple cabbage juice, or do what I do and dip coffee filters in it then cut into strips and let them dry. This will give you PH paper. I posted some color charts in the attachments...

:D
I almost dropped one when I read that.
I kind of figured as much. I am not a rocket scientist, but could kind of tell it is a conductivity measurement device and that wetness, density, etc. would skew it.
So, the PH of the liquid in the sub = the PH of the sub? I will get the test strips and rock them out.
Thanks!
