My Hanna's been ok - it was around 40-50 USD. I'm sure you could get a better one, though. I've been pretty good about calibrating it. I haven't used an Oakton. Some people have had good luck with finding a meter at places that sell beer-brewing supplies. YMMV, Mike > Joshua, > > I woul

Joshua, I would suggest a Oakton ultra basic PH tester. If you visit you local hydroponics shop I am sure they will have one for you. I suggest staying away from a Hanna meter. Aidan 1990 VW Jetta on WVO four years + [EMAIL PROTECTED] wrote: >Hello, >Im making some biodiesel and I'm
