Buying Guide for a pH meter

[Hermit]

I've used mine for about 5 batches. No complaints.

I just replaced my Milwaukee PH55 with the MW101 because of this thread and I am very pleased with it. The MW101, that is. The PH55 only reads to a tenth, rather than a hundredth, and seemed to be easily confused. Also, the calibration procedure was a real pain. Right out of the box my MW101 read 7.04 when testing the 7.01 solution and 4.03 for the 4.01 solution. Close enough.

Anybody have any experience with this Omega meter? $95 gets you a great meter (according to specs of course) and it includes a carrying case and calibration solutions. It also has a higher max temp on ATC than other meters, despite Kai's words of wisdom on ATC.

One thing bothers me about the spec sheet and that is the line "1-Keyboard Calibration". What does that mean? The only thing I can think of is that it means single buffer calibration in which case I'd avoid it but I don't know that this is what the phrase means. I guess you could call and ask.

ATC is important but you do not want to stress it. You wouldn't want to use it much above 80-90 °F so the fact that this unit is rated to 90°C is immaterial.

The specs do seem great on the pH meter, but I have no clue about it's real world performance. The price is exceptional given the case, buffering solution, etc.

Yeah, 1-keyboard calibration makes no sense to me. The kit does come with 2 buffering solutions, but it doesn't indicate whether it's 1 point or 2 points in the spec sheet. I called and spoke with the sales person, but he was clueless and said that the technical support staff was gone for the day.

In the book, Water: A Comprehensive Guide for Brewers, they have a guide for pH meters which I list in this thread. I'm currently looking for recommendations based on those specs.

I ended up buying this meter and it's great. It is definitely 2-point calibration, and what I think they mean by 1-keyboard is that you only have to push 1 button. It's automatic after that. Anyway, I would recommend it for sure.
