Why the Marine Master
- All-in-one marine testing: measures alkalinity, calcium, magnesium, nitrate, nitrite, phosphate, phosphorus, pH and more, so one meter covers the parameters that matter most in a reef tank.
- Wireless data logging: connects to the free Hanna Lab app over Bluetooth for real-time logging, graphing, and easy trend tracking on your phone or tablet.
- Reef-safe accuracy: advanced LED-based optics deliver precise, repeatable readings built for saltwater aquariums.
- Waterproof and rugged: a sealed, portable housing stands up to splashes and drips around the tank.
- Replaces multiple kits: one photometer does the work of many separate checkers and titration test kits.
