Hanna Marine Magnesium Checker HI783

The HI783 Marine Magnesium Checker HC is a handheld colorimeter that uses the Beer- Lambert principle to determine the concentration of magnesium colorimetrically. The HI783 is designed specifically to measure magnesium levels in a saltwater aquarium or in marine biology applications. The 1000 to 1800 ppm range is ideal for coral/fish or fish-only aquarium maintenance.

• Ideal for aquariums and marine biology
• Easier to use and more accurate than chemical test kits
• Small size, big convenience

Range: 1000 to 1800 ppm Magnesium

Resolution: 5ppm
