I-auto Refractometer yokuthwala ifakwe izingxenye ze-CCD ezisebenza kakhulu, ngejubane eliphezulu, Ubuchwepheshe bokutholwa kwesiginali ephezulu nokuhlaziywa kobuchwepheshe, obuhlonywe ngohlelo lokulawula izinga lokushisa lwe-semiconductor Peltier super. Ingalinganisa kahle nangokunembile inkomba ye-refractive (nD) yoketshezi okuhlukahlukene okufana nokusobala, okusobala, okumnyama, i-viscous, kanye nengxenye enkulu yesisombululo sikashukela (Brix).
