53.0 mS Calibration/Reference Fluid

Calibration solution for Pinpoint Salinity Monitor. This 53.0 mS (milliseimens) standardized fluid from American Marine Inc. matches the refractive index of 35 ppt (parts per thousand) seawater, making it an ideal reference solution for refractometers.

• For the most accurate results, precision-testing devices should be calibrated immediately before use.
• The calibration should be checked occasionally to ensure accurate readings.
• Calibration fluid can be re-used if uncontaminated by other fluids and kept in a tightly capped container.
• To ensure the most accurate reading from your refractometer, use the 53.0 µS Calibration Fluid as a reference. This particular solution matches the refractive index of 35 ppt seawater. Simply place one drop onto the refractometer and read the value to determine if your refractometer is properly calibrated.
