Secinājumi:
• Mērot ar ирф – 454 laušanas koeficientu analizējamam šķīdumam relatīvā kļūda ir 0%
• Ar digitālo refraktometru 0,33%.
• Digitālā refraktometra mērījums ir precīzāks, jo tā precizitāte ir līdz 4 zīmem aiz komata un tā jūtību uz gaismu nosaka mēraprāts, nevis cilvēka acs,
• Var secināt,jo lielāks ir gaismas laušanas koeficients, jo lielāka vielas koncentrācija šķīdumā.
