Digital Refractometer for Seawater Analysis

This digital refractometer 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.
  • Designed for seawater salinity analysis
  • High accuracy measurements displayed as PSU, ppt and specific gravity
  • Dual-level LCD displays measurement and temperature readings simultaneously
  • Automatic Temperature Compensation
  • Easy Measurement: place a few drops of the sample in the well and press the READ key
  • Alerts the user of low battery power that could adversely affect readings
  • IP65 Water Protection: built to perform under the harsh field conditions associated with environments containing seawater
  • Readings are displayed in approximately 1.5 seconds
  • Calibrate with distilled or deionized water
  • Sample can be as small as 2 metric drops
  • Automatic shut-off after three minutes of non-use
  • Stainless Steel Sample Well: easy to clean and corrosion-resistant
