The Red Sea Refractometer is designed to test the salinity of seawater at 77 degrees F, with much greater accuracy than refractometers designed to test brine. Automatic Temperature Compensation, high-quality optics and a large display ensure accuracy and ease of use.

Instruction

  • Use Instructions: 1. Clean the glass prism and translucent flap of the refractometer with deionized (DI) water at 22-25°C and dry thoroughly with a soft cloth.2. Hold the refractometer horizontally and open the flap3. Using the pipette provided, place a small sample of the seawater to be tested on the glass prism. Do not immerse the refractometer into the seawater.4. Close the flap on the sample and wait for 15 seconds to allow for the temperature of the sample and the refractometer to equalize5. Point the prism end of the refractometer to a light source and look through the eyepiece. (Note: The refractive index is also dependent on the wavelengthof the light source and therefore a light source close to daylight should be used.)6. The top of the screen will be blue and the bottom will be clear/white. The dividing line between the blue and white sections is where the reading should be taken.7. Adjust the focus for your individual eyesight by rotating the eyepiece until a sharp picture is achieved8. Read the seawater salinity in ppt and/or the equivalent specific gravity (S.G.) at 25°C9. Clean the glass prism and translucent flap of the refractometer with DI water and dry thoroughly with a soft clothCalibration:Alignment should always be carried out with the instrument at 22-25°C. Allow the refractometer to stand at this temperature for 30 minutes before alignment.1. Remove the cover from the alignment screw2. Place a sample of DI water on the glass prism and check the salinity reading as directed above3. If the reading is not exactly on the zero ppt mark on the scale, adjust the position of the reading by rotating the alignment screw with the screwdriver provided until the reading is zero ppt4. Replace the cover from the alignment screw
