Designed for Hardcore Salinity Analysis
HANNA's Seawater Digital Refractometer (HI 96822) is a rugged portable, water resistant device that utilizes the measurement of the refractive index to determine the salinity of natural and artificial seawater, ocean water or brackish intermediates. The Seawater Digital Refractometer benefits from HANNA's years of experience as a manufacturer of analytical instruments. This digital refractometer eliminates the uncertainty associated with mechanical refractometers and is rugged and portable enough to be used at home, in the lab and out in the field.

The Seawater Digital Refractometer is an optical device that is quick and easy to use. After a simple user calibration with distilled or deionized water, a seawater sample can be introduced into the sample well. Within seconds, the refractive index and temperature are measured and converted into one of three popular measurement units: Practical Salinity Units (PSU), Salinity in Parts Per Thousand (PPT), or Specific Gravity (S.G. (20/20)). All conversion algorithms are based upon respected scientific publications using the physical properties of seawater (not sodium chloride). Temperature (in degrees Celsius or Fahrenheit) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.

Key Features Include:

  • IP65 waterproof protection
  • Automatic Temperature Compensation (ATC)
  • Battery operation with Low Power indicator (BEPS)
  • Automatically turns off after 3 minutes of non-use
  • Dual Level LCD Readings - Salinity and Temperature
  • Stainless Steel Sample Well - Resists Corrosion from Seawater
  • Quick and Precise Results - Readings in 1.5 Seconds
  • Single Point Calibration with either Distilled or Deionized Water
  • Small Sample Size - They can be as small as 2 Metric Drops
  • Easy to USE!


Measuring salinity of marine aquariums does not get any easier OR faster than this! Now professional measurement is as simple as dripping sample water onto the prism surface and pressing the READ key. In less than 2 seconds, this outstanding precision device will display the results in clear, digital numbers on the LCD screen. Dual-level LCD shows measurements in Practical Salinity Units (PSU), Salinity in Parts Per Thousands (PPT) or Specific Gravity S.G. (20/20). Automatically compensates for temperature for accurate research-grade analysis. Rugged, water-resistant unit boasts compact design and operates on a 9V battery (included) for wire-free portability. Features low battery-life indicator and shuts off automatically after 3 minutes of non-use to preserve battery life. Digital Seawater Refractometer measures only 7-1/2" x 4" x 2-5/8" high.
