Marine Magnesium Checker HI-783 – Hanna

Product details

Marine Magnesium Checker HI-783 – Hanna is a handheld colorimeter (Hanna’s Marine Magnesium Checker® HC, model HI783) designed to measure magnesium in saltwater aquariums. Instead of matching a sample to a color chart, it uses digital optical measurement with a built-in reaction timer to help you get consistent magnesium hardness readings in ppm.

• Handheld colorimeter approach helps eliminate manual color-chart matching for magnesium testing.
• One-button operation makes the workflow straightforward and repeatable.
• Built-in reaction timer supports consistent timing across samples.
• Designed specifically as a marine magnesium checker for reef and saltwater aquarium use.
• Uses a reagent-based procedure with the instrument measuring the sample after the set reaction time.
