Hanna mg checker

[mattb2989]

Has anyone got the new updated version of the mg checker. I have mine. How accurate have you found yours? After half dozen tests the reagent A bottle is already crystalizing. Accuaracy is about 150ppm higher than salifert for me

How many times did you repeat the Salifert test? I ask because 150 ppm is about the size of the spread in results for Salifert.

3 times. Salifert came up 1350 1350 and 1320. Hanna gave 1460 1470 1450

Great data. I guess a standard would be the only way to sort out which test is more accurate.

The salifert ties in with my ladt icp. Im dosing 2ml mg a day on a 300. It is impossible to have the mg level at what the hanna is stating with dosing the 2ml a day anyway even if there was no uptake it jist wouldnt get to those figures
