Περιγραφή Προϊόντος

The  vast  majority  of  refractometers  currently  available  to  the  hobby  are  designed  for measuring saltwater (sodium chloride or brine solution) and not true ‘seawater’. Although seawater is mostly sodium chloride it also contains other elements such as magnesium and calcium that change the refractive index slightly and will give a different and incorrect results.
