Thanks! I got a card with my test solution but the liquid in the ph solutions leaked on the card in the mail and I haven’t got new solution yet. Probably something I should do.
Glad you gave me the info on the two-point calibration and glass bulb. I was looking at a cheapy, but will follow your suggestion. They are definitely more expensive so I will have to save a little longer, knowing that my current method is acceptable. Again, thanks for the info. Like all my other hobbies, this is turning into a passion very quickly especially considering that I can’t imbibe anything right now due to a new policy of random testing at work and at the Dr’s office since I am on opioids for pain relief. Hopefully, all of those conditions will disappear soon.
