The Red Sea Refractometer - R12018 is an advanced instrument designed specifically for measuring the absolute salinity of seawater at a standard reef aquarium temperature of 25°C (77°F). This precision device eliminates the need for seawater or temperature compensation factors, as it is calibrated precisely for natural seawater (NSW). Unlike traditional refractometers that are typically calibrated for brine (NaCl solutions), the Red Sea Refractometer provides you with direct and accurate salinity readings specific to the ionic content of seawater. This ensures that you are measuring the true salinity, which is crucial for maintaining a healthy and thriving reef aquarium.

Most refractometers in the aquarium hobby are not tailored for reef aquariums and use an algorithm meant for brine rather than actual seawater. This can lead to measurements that are off by up to 1.5ppt, potentially impacting coral health and colouration. The Red Sea Refractometer addresses these issues by providing a higher resolution display that focuses on the range applicable to reef aquariums, specifically up to 40ppt.

Furthermore, it features integrated Automatic Temperature Compensation (ATC) for consistently accurate readings, even at varying ambient temperatures, making it an indispensable tool for serious aquarists who need reliable and precise measurements.

Key Features:

• Directly reads absolute salinity at 25°C/77°F, eliminating compensation factors.
• Calibrated for seawater’s ionic content, offering exceptional accuracy compared to brine-calibrated refractometers.
• Higher resolution display optimised for reef aquariums, up to 40ppt.
• Integrated Automatic Temperature Compensation (ATC) for precise readings.

By using the Red Sea Refractometer, aquarists can confidently monitor and maintain the ideal saline conditions necessary for vibrant coral growth and overall reef health. The accuracy and specificity of its design make it a recommended choice for those serious about properly managing their marine ecosystems.
