Basic tools:


Salinity measurement is easy with various tools such as hydrometers, salinity refractometers and electronic meters.

Some electronic meters allow salinity measurement, but only read to 10 ppt. In marine applications with salinities up to 45 ppt, the meter purchased needs to cover the full range. The below Extech salinity meter can measure to 70 ppt.

Meters for salinity range from multi-parameter meters that read most or all parameters that you wish to test, to simple and affordable meters.


Features: essential tool for salinity

Measure Salinity in aquaculture, environmental studies, ground water, Koi ponds, irrigation, drinking water, and other applications.
