I've been having issues with my Trident matching my Hanna Checker for alkalinity. The Hanna Checker is always 1 point higher than the Trident. Right now the Trident says my alk is 7.3 but the Hanna Checker says 8.3. If I test Neptune's calibration fluid with my Hanna Checker I get 1 point higher than what is listed. I bought a new Checker, with new reagent and I get the same answer. The Trident is "new" being swapped for my old one with Neptune's maintenance program. I was having the same issue with the old Trident though, and since it was operating for 2 years I swapped it out hoping that would fix things.
I don't know which value to believe. I am uncomfortable with an alk of 7.3 preferring a value in the mid 8s. I've been searching for the fauna marin calibrator but it's out of stock everywhere. Anyone else with a Trident having this issue?
