Refractometer for Testing Percent NaCl, Sodium Hydroxide, Hydrochloric Acid, and Sodium Sulfite.


Very interested, yet ignorant about this technology. I need reliability in testing % NaCl in water softening applications as well as concentrations of sodium hydroxide, hydrochloric acid, and sodium sulfite. Do I need multiple instruments? Can I get the meter to read in ppm of sodium sulfite? Can the meter(s) read in % saturation of NaCl? I am used to reading hydrometers for all but sodium sulfite, can the instruments give the same read out in % acid or caustic? I really do not understand the BRIX scale and how that will look when all I want is the strength of acid or % saturation of NaCl. Thanks,
