Salinity meter


Measure for salinity. While an appropriate concentration of salts is vital for aquatic plants and animals, salinity that is beyond the normal range for any species of organism will cause stress.

We also sell a salinity refractometer. The advantage of the salinity meter is its accuracy with precise digital readings. Regular maintenance and calibration required (solution will be mailed to you after one month). The advantage of the refractometer is easy calibration and less maintenance. See more details below.
