What is the Hanna Marine Master Multiparameter Photometer Kit?
The Hanna Marine Master Multiparameter Photometer Kit is a portable, all‐in‐one water testing solution designed for saltwater aquariums and marine biology applications. It accurately measures multiple critical parameters such as pH, alkalinity, calcium, ammonia, magnesium, nitrate (LR & HR), nitrite (ULR), and phosphate (ULR). Designed with both hobbyists and professionals in mind, it ensures proper aquarium maintenance through advanced optical technology and user‐friendly features.
Key Features:
- Measures 9 essential parameters: pH, Alkalinity, Ammonia, Calcium, Magnesium, Nitrate LR & HR, Nitrite ULR, Phosphate ULR
- Advanced optical system ensures lab‐quality accuracy
- Tutorial mode and CAL check for user guidance and validation
- Logs up to 50 measurements with Log Recall function
- IP67‐rated waterproof and drop‐resistant design
- Portable with over 800 measurements per battery set
- Comes in a durable carrying case with key reagents and accessories
