pH measuring instruments

[Zopilote]

Can anyone recommend a good pH measuring device
and a reputable dealer who sells it?

Thanks for your input.

The PinPoint pH meters seem to be fine. There are lots of online vendors. I've ordered from DrsFosterSmith.com, PremiumAquatics.com, MarineDepot.com, and probably a few others. I use an Oakton pHTestr3+ that I got from LabSafety.com. It's more expensive, though. There are a number of very inexpensive meters on EBay. The ones from Hanna seem okay.
