I am new to PH so bare with me, please.
I bought this one...
http://www.ebay.com/itm/Milwaukee-p...052?pt=LH_DefaultDomain_0&hash=item19eae0e2bc
I calibrated it yesterday to 7.0 as instructed. I tested my input water and the calibration solution back and forth to make sure it was consistent.
I store it in a jar of Deer Park Spring Water at about 6.8PH.
This morning, I checked my run off and it was 6.2PH. When I put the meter back into the spring water, I noticed it was reading 6.2 and didn't change.
I put it in the calibration fluid and it went to 6.1. So, I re-calibrated to 7.0 and put it back into the Spring water. It went to 6.8 (like yesterday) and stabilized.
Should I re-calibrate every day? How long does the calibration solution keep a 7.0?
Thanks
