The model C10 Abbe Refractometer is an excellent instrument for the Refractive Index (nD) analysis of liquids, glass, plastic, and film. Operation consists of placing a sample on the prism; while looking through the eye-piece, the control knob is turned until the shadowline is centered in the crosshairs. The reading is taken when the vertical line crosses the scale. Calibrates with water. Primary features consist of an oversized, easy-to-read scale; digital analysis and readout of prism temperature; Refractive Index (nD) & Brix scales; primary & secondary prisms; color compensator dial; large measurement dial focusable eyepiece. For prism temperature control, the C10 comes equipped with 2 circulator nozzles for the primary prism and 2 for the secondary prism; which enables this refractometer to be connected to a circulating bath to accurately regulate prism temperature. The prism temperature is displayed on the LCD display at the base of the refractometer. The effective temperature range is 0 to +70°C.
