We're all trying to be good homebrew soldiers by taking good notes and good measurements. But there can be a frustration factor when your tools and instruments either aren't giving you a straight answer or a wrong answer, and that is mucking up your brew day. First, we correct ourselves and do the actual proper procedure to measure the pH of brew day liquids. Then we grab the rest of our measuring devices and get them calibrated the right way. Life is better when brew tools tell the truth!
