Just putting it out there if anyone uses these for their Alk testing that there's a problem going on with the reagent & maybe treat your readings with caution.
Mine was giving out values about 1dkh+ lower compared to a couple of differant Salifert kits as well as their check solution.

Out of the US & now Hanna SA have confirmed knowledge that the seal in the lid once the bottle is opened is causing some change to take place,apparently its been dealt with but the stock that is here isn't the corrected bottles yet.
