Mystery Solved! regarding pH measurements

I need to give a cheese to Sailor con Queso for helping me to solve a mystery regarding my pH meter readings. I have been lucky enough to bring home milk from a farm! But I thought I was doing something wrong in collecting or transporting the milk home because my pH meter after calibration was showing 6.5 before starting my make. I felt like I was chasing the pH the entire make each time...
Sailor suggested taking the pH meter to the source! So I calibrated my Hanna 98127, and took it to the farm. The milk straight out of the cow measured 6.5!
So today I am the proud owner of an Exstik 100 !! It seemed a good excuse!
And THANK YOU to Sailor!

You'll love the Exstik 100! Keep a bottle of 4 & 7 calibration and you'll be just fine. With the Exstik100, you can measure curd PH after a press. Great purchase!

Yea, Susan!

I'll echo what Eric said...I love my ExStik 100 too!

Once you get it settled down and working consistently well, it makes everything so much clearer.

Let's ferment something!
Bread, beer, wine, cheese...it's all good.

Glad you got to the bottom of it Susan (and Sailor) and a cheese for both of you for the discovery ;).  The Extech ExStik is, as far as I can find, the only pH tester anywhere near it's price range with a flat electrode that can measure both liquids and solids.  I've seen a few probe sensor that can do solids they leave a mark (hole) and they're $200 and up.  For that reason we've decided the pH100 is the only tester we are going to carry.  I still have my beloved Oakton pH2 (actually it's my 2nd because the first one had a cracked housing) and it is satisfactory, but for $30 more the Extech is worth it.

By the way (and just slightly off topic) if you're really interested in seeing what's going in your cave as far as temperature and %RH are concerned you may want to look at a humidity / temperature USB datalogger.  Extech sells one and so does Lascar for the same price.  I've used both, and while Extech makes a great pH tester the Lascar datalogger is in my opinion superior and has a better data downloading interface.  The data you get over a longer time interval can help diagnose problems.
