This is a true seawater or a salt (brine) refractometer preferred by the aquarist. Designed to measure seawater (marine aquaria) or very low concentrated salt solutions 

It can be generally calibrated by fresh water but to ensure accurate salinity measurement of a reef aquarium, calibrate at least once by a solution matching the refractive index of 35ppt seawater or similar solution near measurement range. 

With this refractometer you can: 

  • Measure concentration of salt water and brine or salinity in water
  • Used for quality control in research, clinical laboratories, and marine industry
  • Have better management of marine saltwater tank
  • Ensure pets are safe in your aquarium
  • Ensure water has the exact level of salinity they need to survive and thrive in their typical marine environment 

With few drops on the testing prism, cover, look and read the result!
