Hello,
I have a new PH meter which I calabrated 2 nights ago when it arrived. The amount of 6.86 and 4.00 solotion provided is so litte that I put it back into its litte bottles.
I am mashing today and thought I'd just check the PH meter to make sure its still calabrated. Instead of reading 6.86 in the buffer it read 7.3.
So the question for me now is do I re calabrate using this used buffer, or do I just trust my original calabration (2 days ago).? 5 points is a big deal in the mash, so I must choose wisely.
Thanks
David
