Red Sea Red Sea Seawater Refractometer

Product Description

The Red Sea Seawater Refractometer, a high-precision saltwater refractometer

• Instantly measures the absolute salinity of seawater at 25°C (no compensation factors for seawater or temperature required)

• Specially calibrated for the ion content of seawater and designed for precise salinity measurement. (Most standard refractometers are calibrated only with a standard salt solution (NaCl))

• Seawater calibration at 25°C (standard temperature for saltwater aquariums; most standard refractometers are calibrated at 15°C)

• Easy to use thanks to an easy-to-read, high-resolution display with a measurement range up to 40 parts per thousand (ppt), which is important for seawater.

• Easy calibration using reverse osmosis water.

• Includes automatic temperature compensation (ATC) for accurate measurements regardless of room temperature

The Red Sea Seawater Refractometer offers exceptional accuracy, designed to determine absolute salinity at a temperature of 25°C.

To eliminate measurement errors, the refractometer has been calibrated to 25°C, as room and water temperatures can affect the measurement result. The prism’s special seawater calibration ensures additional measurement accuracy. Compared to standard refractometers (NaCl calibration), deviations of up to 1.5 parts per thousand (?, ppt) can occur when measuring seawater, which can affect coral growth and coloration.  The main features of the new refractometer are:
