Description: Brightwell Aquatics Refractometer Calibration Standard is a professional-grade solution designed to provide an accurate reference for the calibration of seawater refractometers, hydrometers, and other density measuring equipment. Ensuring your equipment is correctly calibrated is critical for maintaining the health and stability of your marine or reef aquarium. This solution is specifically formulated to match the refractive index of 35 ppt seawater at 25°C, providing a reliable and precise calibration point.

Specifications:

• Specific Gravity: 1.0264

• Refractive Index: 1.3394

• Salinity: 35 ppt

• Conductivity: 53 mS/cm at 25°C

Instructions:

1. Clean the refractometer prism with fresh water and dry thoroughly with a soft cloth.

2. Place a few drops of Refractometer Calibration Standard on the prism.

3. Wait 30 seconds for the temperature to stabilize.

4. Adjust the calibration screw until the refractometer reads 35 ppt or a specific gravity of 1.0264.
