This unit is a precision optical instrument that allows for the rapid and accurate determination of the refractive index of liquid solutions. It will specifically assist in determining the percent residual of oil remaining in a refrigeration system when converting it to a new refrigeration oil. Such retrofits require converting the mineral oil to a polyol ester (POE) or polyalkylene glycol (PAG), an alkylbenzene lubricant (Zerol) to a POE, or a mineral oil to an alkylbenzene.
