Product Questions

Is the new version with the 3 minute countdown and powder packet instead of the liquid?
Question by: Mario on Nov 3, 2022, 9:43 PM
The Hanna Instruments Marine Magnesium Colorimter has been updated with the timer. The reagent kits are liquid https://www.bulkreefsupply.com/hi783-25-marine-magnesium-reagents-25-pack-hanna-instruments.html.

Is this magnesium checker the new updated version? The one that comes with a 3 minute timer and powder packets that replaced the bad liquid that was used or original
Question by: Mario Lopez on Nov 2, 2022, 9:30 PM
Thanks for the question! The checkers we have are the new updated version at this time. The old ones were returned to Hanna once they made the recall and are not available any longer. Please let us know if we can help with anything else!
