The HI97115UC Bluetooth Marine Master Multiparameter Checker from Hanna Instruments is a professional-grade testing solution designed for serious reef hobbyists and aquarists. This compact device measures nine essential marine parameters, including pH, alkalinity, ammonia, calcium, magnesium, nitrate (low and high range), nitrite (ultra low range), and phosphate (ultra low range). Its advanced LED optical system ensures digital accuracy, delivering precise results that match laboratory standards, eliminating the guesswork associated with traditional color-matching test kits. The Marine Master also features Bluetooth connectivity, allowing users to log data on their smartphones or tablets through the Hanna Lab App.
