I have a Spartan refractor Model a 300 cl that is used to measure Serum Protein/Urine Sp it has 3 scales at 20Degress 1. wt s.p. scale 0-12(left) 2.ND 1.335-1.36 ( middle) 3.U.G 5-50 (Right) Can it be used to measure salinity? how would I convert the scales? It is heavy duty/high quality equipment(ebay)... I was thinking if I could find water at 1.026 and test it, it would give me a Base Line or I'm... I way off base myself...Thanks EDDIE
