meter just came in yesterday. I ordered both the TDS
meter from the same person to save on shipping.
I need help trying to calibrate the ph
meter. It says that I need to get 7.01 buffer fluid. Is this necessary and how do I do it?
The instructions also say to store the electrode in HI 70300 Storage Solution and not to use DI
or Distilled water. Do I really need to store it in the "Storage Solution" and why can't I use DI
or Distilled water? And if I need the Storage Solution, where can I buy it???
