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
