What is the Hanna Marine Master Multiparameter Photometer?

The Hanna Marine Master Multiparameter Photometer is a handheld, professional‐grade Photometer designed to deliver fast, accurate measurements of critical water parameters in saltwater aquariums and marine biology settings. It combines lab‐level accuracy with an intuitive, portable design for both beginners and advanced users.

Key Features:

  • Measures 9 critical marine parameters with lab‐quality accuracy
  • Advanced optical system with LED and interference filter for precision
  • Portable, waterproof, and floats if dropped in water
  • No warm‐up time; ready to measure instantly
  • On‐screen tutorial mode for step‐by‐step guidance
  • CAL check system for easy performance validation and calibration
  • Auto‐off and low battery warning features
  • Data logging for the last 50 measurements
  • Durable, shock‐resistant design with positive cuvette locking system

These features make the HI-97105 especially useful for maintaining reef health, preventing imbalances, and optimising water conditions for coral growth and marine life sustainability.

What are the features and benefits of the HI-97105 for marine testing?
