Automatic Petroleum Refractometer

Refractive index is a fundamental physical property that is used in conjunction with other properties to characterize pure hydrocarbons and their mixtures. It is a useful property for concentration measurements, purity determinations and chemical identification. Conforms to ASTM D1218, D1747, D5006, ISO 5661 test specifications Electronic heating and cooling Peltier system eliminates the need for a circulating water bath Automated and precise refractive index measurements Rugged sapphire prism Designed for samples ranging from clear to highly colored, dark and opaque Clear graphical LCD display with on-screen instructions and full menu operation Multipoint calibration routines maximize accuracy RS232C and centronics communication ports Measurement Scales: Refractive Index (RI), BRIX (% sucrose), Temperature Corrected RI, Temperature Corrected BRIX, Ten User-Programmable Scales Illumination: 589 nm light emitting diode with interference filter (estimated life: 100,000 hrs) Range: Dissolved Solids: 0 to 95% solids Refractive Index: 1.29000 to 1.70000nD (nD - Sodium D-Line Refractive Index) Readability: Standard Mode: 0.1% Solids 0.0001nD Extended Mode: 0.01% Solids 0.00001nD Precision: Standard Mode: ±0.02% Solids ± 0.00002nD Extended Display Mode: Refractive Index Standard Oils ± 0.00002 - Typical clear aqueous samples, % Solids Temperature Compensated, as sucrose ±0.02% Calibration Fluid: refractive index standard oil, NIST traceable nominal value 1.495 RI, 67.61 BRIX Sample Types: Transparent, translucent or opaque Prism Assembly: Stainless steel, synthetic sapphire sealed with solvent-resistant epoxy Calibration: 1 point - Water only; 2 point - Water and refractive index or Brix standard Readability: Standard Mode: 0.1% Solids 0.0001nD Extended Mode: 0.01% Solids 0.00001nD Precision: Standard Mode: ±0.02% Solids ± 0.00002nD Extended Display Mode: Refractive Index Standard Oils ± 0.00002 - Typical clear aqueous samples, % Solids Temperature Compensated, as sucrose ±0.02% Calibration Fluid: refractive index standard oil, NIST traceable nominal value 1.495 RI, 67.61 BRIX
