Abbeder refractometer waa qalab awood u leh inuu go'aamiyo hufnaanta, dareeraha hufan, ama index refractive adag ND iyo kala firidhsan fidsan ND-NC (kaas oo inta badan ay ku jiraan dareeraha hufan inta badan), sida heerkulbeeg ku xiran qalab, heerkulka waa 10 ° C. Tilmaanta refractive ND ee ah 50 ° C. Isticmaal muuqaal, akhrinta kaadhka shahaadadda indhaha, iyo tirada heerkulka ayaa la soo bandhigay, oo fudud oo la isku halayn karo. Saldhiggu waxa uu ka samaysan yahay bir aan bir lahayn, priism-kuna waa muraayad adag, taas oo aan fududayn in laga walwalo.
