Professional-Grade Reef Testing in One Powerful Device

Simplify reef aquarium testing with the Hanna HI97115UC Bluetooth Marine Master Multiparameter Checker Kit. Designed for serious reef hobbyists, coral growers, and aquarium professionals, this advanced handheld photometer combines the accuracy of laboratory-grade testing with the convenience of a single portable instrument.

Instead of purchasing multiple digital checkers, the Marine Master measures nine essential marine water parametersusing one compact device. Built-in Bluetooth connectivity allows you to pair the checker with the Hanna Lab App, making it easy to log results, track trends, assign testing locations, add notes, and share water test data directly from your smartphone or tablet.

Featuring Hanna's advanced optical system with precision LEDs, interference filters, and a reference detector, the Marine Master delivers highly accurate, repeatable results while eliminating the guesswork of traditional color comparison test kits. Its waterproof IP67-rated floating design, built-in tutorials, and CAL Check™ validation system make testing faster, easier, and more reliable than ever.

Whether you're maintaining a mixed reef, an SPS-dominated aquarium, coral propagation system, or professional service route, the Marine Master provides everything you need to monitor your aquarium with confidence.
