Default Proper pH measured mashing, here I come!

I just got this on eBay! $25 total...it appears to be used. Hopefully it's as advertised.

Compare with this new one...$200!

If I hadn't won that one, I would've gotten one of these. Looks like a good deal, also. AHB sells them for $60.

Nice!

I really need to start paying closer attention to PH. For now, I'll use the buffer and forget about it.

I want to start looking at PH too, but it seems like the meters are a PITA to use, and the strips are not that accurate - the colors all look damn near the same between 5.2 and 5.7 on the strips I have. Maybe I need new strips

That's a great deal. Wow. I am envious.

I have hard water that is low in calcium, so I am starting to think about mash pH for lighter beers. I was thinking of using a pH meter and adjusting with acid, so I would be really interested to hear how you like using this. I assumed they would be great, except MA Brewer says they can be a PITA. It would be good to hear what others think.

No, you are using the $1 ones I use. Made to test rain water or something.

It makes good beer so who gives a flyin ...?

Yes, please listen to others! I don't even own one, because I *think* it will be a PITA to have - you have to calibrate it each time, with two different solutions I think, and then store it in a special solution. Then, the measurment tip only lasts about a year, and costs $45 or so to replace - that is my understanding, anyway.

Calibration takes almost no time at all, just need to make sure you've got the buffer solutions ready! This seems like a nice find, let me know how it works!

Here is a pH sensor for $78 that one could easily integrate into the mash monitor microcontroller system. One could monitor the temperature of the mash as well as the pH.

This sensor works to 80C (176F). You have to be careful when looking at these things because some of them are not rated for high temperatures.
