Ph meter customer service.

You should be calibrating it every day you use it.

 

Dending on the meter, check it for drift every couple of hours.

 

Yep. EPA method protocols mandate calibrating every 2 hours... and that is generally for expensive meters, many of which cost more than my brewhouse.

 

I don't have a pH meter at home. But I use them at work. If and when I get one for brewing, I'll probably calibrate before brew, and then just do a check with the buffers at the end of brew.

 

Good practice if you log the pH going into the fermenters.

 

Yeah I really want to get one. I never get a good hot break and I'm wondering if it has to do with the pH. My efficiency is fine. I currently use bru'n water for my water additions and just rely on the number it gives me.

 

What does it measure with a known reference? Or do you know that this Gose should have a pH higher than 2.9? (And was it still carbonated, which lowers ph?) I mention this because I suspect a typical Gose pH (or a lot of sours for that matter) might be in the very low 3's.

 

A guy in the club went through 3 Hanna Checkers to get one that calibrated on the solutions. Buyer beware.

 

The meters were off, he could not calibrate to the solutions.
