Marine Magnesium Checker HC HI783 (Saltwater) AutoAqua Voltage / frequency: 230V/50Hz (115V/60Hz)The testing process is the same as Alkalinity HI772 with one second liquid reagent. 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.
