What is the Hanna Marine Monitor For pH, Marine Salinity, and Temperature?

The Hanna Marine Monitor For pH, Marine Salinity, and Temperature is a compact, waterproof system designed for continuous monitoring of key water parameters in saltwater aquariums, aquaculture, and seawater applications. It measures and displays salinity (ppt, PSU, or S.G), temperature, conductivity, and pH, all on a clear LCD screen. With built‐in temperature compensation, selectable units, and a reliable alarm system, it ensures stable and accurate readings essential for aquatic life.

Key Features:

  • Real‐time monitoring of salinity, pH, conductivity, and temperature
  • High/Low alarms with acoustic alerts for each parameter
  • Replaceable double‐junction pH electrode with chemical resistance
  • Built‐in temperature sensor for fast, accurate readings
  • Auto temperature compensation for precise measurements
  • Dual pin graphite EC probe
  • Compact and waterproof (IP rating) with vertical mounting

What are the features of the Hanna Marine Monitor For pH, Marine Salinity, and Temperature that benefit marine aquarists?

The Hanna Marine Monitor was engineered with the needs of saltwater enthusiasts and aquaculture professionals in mind. It delivers stable, high‐accuracy readings with intuitive operation, smart calibration, and robust build quality. Its simple setup and comprehensive measurement capabilities make it ideal for long‐term monitoring in marine environments.

This device supports multiple salinity units, ppt, PSU, and S.G., to meet different user preferences and standards. Its integrated alarm system warns users if values stray outside acceptable ranges, helping to prevent issues before they become problems. The compact body, splash‐proof keypad, and dedicated calibration/setup buttons ensure reliability and ease of use even in demanding environments.
