Just want to share that Hanna’s instruments has “standard solutions” for many of their testers. (I recently found out). And I don’t think many know about it.
I’ve owned 4 Hanna tester for almost 2yrs and using these standard solutions, i was able to check if my testers are still within the given range including calcium tester.
