With the Hanna pH/EC/salinity monitor for aquariums, you acquire a professional and reliable solution for continuously monitoring water quality in your marine aquarium. This advanced measuring instrument is specially designed for demanding aquarium enthusiasts and top-level aquariums, where accuracy and ease of use are essential. Thanks to the combination of pH, conductivity, and salinity measurements, you are assured of a stable and healthy living environment for your precious fish and corals.

Always have insight into your water values

The Hanna monitor offers continuous and real-time measurements of the three most important parameters in saltwater aquariums: pH, conductivity (EC), and salinity. The large, easy-to-read LCD display clearly shows all values, allowing you to intervene immediately in case of deviations.

• Continuous monitoring of pH, EC, and salinity
• Values easy to read on the display
• Alarm settings for high and low values per parameter
• Immediate acoustic alarm upon exceeding set limits

Reliable technology for stable results

The monitor is equipped with a high-quality dual-junction pH electrode (HI-1286) and a two-electrode EC probe with an integrated temperature sensor. This guarantees fast, stable, and accurate measurements, even during intensive use. Automatic temperature compensation ensures that your measurements are always correct, regardless of the water temperature.

• Automatic temperature compensation (ATC)
• Double junction pH electrode: less susceptible to clogging
• Robust PEI resin housing: easy to clean and resistant to harsh substances
• EC probe with direct temperature measurement for extra precision

User-friendly and flexible to set up

The Hanna HI981520 is designed for ease of use and quick installation. A dedicated setup and calibration button allows you to effortlessly navigate the menu and start a one- or two-point calibration for pH and EC. The compact housing and convenient suction cups enable mounting in virtually any aquarium.

• Intuitive operation via splash-proof keypad
• Choose your desired unit: ppt, PSU, or Specific Gravity
• Including all necessary calibration and cleaning fluids
• Operates on a safe 12 VDC adapter (included)

Perfect for saltwater aquariums and aquaculture

Whether you manage a professional marine aquarium or have a high-quality home setup, this monitor ensures reliable control over water quality. The system is ideally suited for seawater, saltwater aquariums, and aquaculture applications, where constant monitoring is of crucial importance.

• Salinity measurement range: 0.00 to 80.00 g/L (ppt) or 0 to 42.00 PSU
