Product Code: RSS31102

Description
 
Many refractometers currently available to the aquarium hobby are designed for measuring saltwater (sodium chloride or brine solution) and not true ‘seawater’. Although seawater is mostly sodium chloride it also contains other elements such as magnesium and calcium that change the refractive index slightly and will give a slightly different result. D-D’s Refractometer adjusts for this difference and gives true salinity results (when correctly calibrated).

Features:
  • True calibration for seawater measurement
  • A New finer scale running from 20-40 ppt salinity (SG 1.015 - 1.030)
  • 20/20 calibration at room temperature for more consistency and accuracy in everyday use
  • Full ATC (auto temperature compensation) ranging from 5 to 30 degrees Celcius
