Jeremy,
pH meters go out of calibration extremely fast and without proper
calibration with trusted calibration fluid you can be off in the order
of magnitude range. Until you get fluids, I would recommend using
paper strips as they are more reliable than an uncalibrated pH meter.
I am fairly
Hello Jeremy.
Some pH meters have microprocesor with values for calibration with 3
specific buffer solution of a given pH value stored in their memory. I
remember some 10 years ago, I used a german Hanna pH meters have this
feature and if I was trying to use standar buffer solution of 4.00 ;
cheaper, and needs no calibration, other than a little practice.

Um, dunno. Why would that be useful?
I have made a good batch of BD using virgin oil, and have made alot
of soap with wvo because my meter is off calibration.
