Salinity (sodium chloride) Formulations
“ppm” parts per million (milligram Sodium per kilogram solution)
Salinity standards are formulated from sodium chloride to approximate ocean and brackish water, brine,
etc., and are used in process water control and oceanography and limnology. There is often confusion
about measuring salinity. Salinity is measured by conductivity with a meter calibrated with
concentration standards (ppm) or parts per million, approximately equal to milligrams per liter.
For example: 100 ppm Salinity Standard is 100 milligrams of sodium chloride per liter of standard.
Custom standards, at other levels. are available on request, simply let us know what you need.
