Hanna has just announced 2 new Marine Checkers for testing marine aquarium water. The new Checkers (electronic water testing devices) are designed to test for Magnesium and Ammonia.

For a long time Hanna has been teasing the Magnesium Checker and it’s finally about to hit retail store shelves. Both Checkers are map priced at $59.95 and we expect the see the Magnesium Checker become as widely used like the Alkalinity, Phosphate, Nitrate and Calcium checkers. The Magnesium Checker (HI783) will accurately measure (±5% of reading @ 25 °C (77 °F) Magnesium levels between 1000 and 1800 PPM and the steps are simple and straightforward as show below.
