Reviews Marine Aquarium Salinity Meter

ZRM&E Seawater Hydrometer for Aquarium Aquaculture Seawater Densimeter Ocean Hydrometer Salinity Meter for Fish Tank Salinity Specific Gravity Test

  • Made of high quality plastic, aquarium transparent, automatic accurate reading brine hydrometer.
  • Accurate, durable and easy to read salt and specific gravity of your marine aquarium, small and waterproof. If the specific gravity is between 1.000-1.019, it indicates that the specific gravity is low.
  • if the specific gravity is between 1.020-1.023, it indicates that the specific gravity is normal.
  • if the specific gravity is between 1.024-1.030, it indicates that the specific gravity is high.
  • The external range of the scale indicates salinity (PPT), and the internal range of the scale indicates gravity. And clearly mark the safe area. Application range: 0-40 degrees (1.000-1.030). If the salinity PPT is between 32-40, it indicates that the salinity is high.
  • if the salinity PPT is between 27-31, it indicates that the salinity is normal.
  • if the salinity PPT is between 0-26, it indicates that the salinity hydrometer is low.
  • Wide range of applications: Suitable for salt water and sea water fish tanks. Perfect for testing salinity and specific gravity of saltwater and seawater tanks, including solubility and specific gravity scales. Suitable for fresh water and sea water.
  • Easy to read swing arm pointer and ultra wide stable base can provide accurate test results.
