The Red Sea REEF-SPEC Refractometer is a laboratory-grade testing instrument engineered specifically for measuring the absolute salinity of marine reef aquariums. Unlike standard industrial refractometers that are calibrated for basic brine solutions (sodium chloride), this device is mathematically calibrated for the exact ionic composition of natural seawater. This specialized calibration prevents common measurement errors that can lead to improper salinity levels in closed coral ecosystems.
Core Technical Specifications
Measurement Scale Range: Displays Salinity from 0 to 40 ppt (parts per thousand) and Specific Gravity from 1.000 to 1.030 S.G.
Resolution Precision: Displays clear increments down to 1 ppt or 0.001 S.G.
Measurement Accuracy: Holds a tight tolerance of +/- 1 ppt or +/- 0.001 S.G.
Display Interface: Designed with a high-contrast internal display matrix optimized for low-light marine environments.
Key Performance Benefits
Seawater-Specific Calibration: Calibrated using the refractive index of natural seawater rather than standard table salt. Standard industrial refractometers can misread true reef salinity by up to 1.5 ppt, which can critically stress delicate hard corals.
Automatic Temperature Compensation (ATC): Features built-in temperature compensation that instantly adjusts the refractive reading based on the ambient sample temperature. This eliminates the need to let water samples sit and cool down to room temperature before testing.
High-Definition Optic Well: Built with a durable optical glass prism nestled inside a corrosion-resistant housing, allowing for quick cleaning and rapid testing.
