Mini Pocket Digital PH Tester

[Jacob]

Really cheap one ...
What do you think guys? Is it worth anything?

[imark]

I've been using them for a couple of years and I think they're fine for checking ballpark pH samples.

i use one of them, no major issues with it. be aware that it can be 0.2 off.
If thats a bit much then look for one of the ones with +/- 0.02 they would be about twice the price.

In that case will go for THAT ONE
