i have managed to get me mitts on a PH meter that has an ATC function built in. I have calibration fluid (4,7 & 10) and have plugged in my Melbourne water profile, grain bill and salt additions into EZ water calc.
I brewed 2 saisons over the past week. same grain bill, water volumes, mash temps etc. I did change salt additions which is why P/H estimates below vary between the brews.
First brew:
EZ water calc estimated room temp PH 5.53
i took a sample after 15 mins and let it cool a little and got a reading of 5.2. ATC read 30.8 degrees
a difference of .33 P/H
Second brew:
EZ water calc estimated room temp PH 5.66
i took a sample after 15 mins and let it cool a little and got a reading of 5.59. ATC read 26.2 degrees
a difference of .07 P/H
I have read from many on here how they get very close or spot on to what EZ calc estimates re P/H and am wondering why my readings are out.
so can I take a reading in any temp sample (not over 50 degrees) and it automatically adjusts it for 25 degrees? So what reading the meter gives is room temp adjusted? There is no instructions with the meter.
any direction or advice would be greatly appreciated.....cheers
