What is the Hanna Marine Master Multiparameter Wireless Photometer Kit?
The Hanna Marine Master Kit is a professional‐grade water testing system designed for marine aquarium and marine biology applications. It includes a multiparameter photometer and a selection of reagents and accessories to accurately measure eight key water parameters: pH, Alkalinity, Ammonia, Calcium, Magnesium, Nitrate (Low Range), Nitrite (Ultra Low Range), and Phosphate (Ultra Low Range). This kit is ideal for use in both field and laboratory environments and can operate as a stand‐alone device or connect via Bluetooth to the Hanna Lab App.
Key Features:
- Compact, waterproof IP67‐rated design with floating capability
- Backlit LCD display with intuitive interface and dedicated help key
- Large 25 mm cuvette size for high‐accuracy readings
- Integrated Bluetooth for data logging, sharing, and enhanced control via the Hanna Lab App
- CAL Check validation and calibration support with on‐screen guides
- Built‐in reaction timer, tutorial mode, and auto‐logging of 200 measurements
- Auto shut‐off after 15 minutes of inactivity to preserve battery life
- Positive‐locking cuvette holder ensures consistent positioning for reliable results
What are the features of the Hanna Marine Master Multiparameter Wireless Photometer Kit?
This kit is built around the Hanna Photometer, a robust, wireless‐enabled instrument capable of measuring multiple marine parameters with high precision. It comes with essential reagents and accessories, including syringes, pipettes, sample cuvettes, and a range of starter reagents for immediate testing needs. The Hanna Lab App enhances the photometer's functionality, offering features like sample naming, note‐taking, advanced logging, and easy data export.
