So, I just tested my alk with my hanna checker that i recently got and got readings of 8.05 and 8.2 and i was expecting low 9's. To double check, i used my salifert kit and got 10.5. Oh boy. I had some salifert check solution which should be 6.7 and the salifert kit read 6.6 with the check and then the hanna read 4.65.
So, it seems like the hanna is a full 2.0 dkh too low? Has anyone had that happen?
