Sper Scientific* Programmable Refractometer - Each

This programmable refractometer comes preloaded with the commonly used Brix (0 to 95%) and nD (refractive index) scales. In addition you may create your own custom scales. An unlimited number of scales can be stored in the softwares database. Transfer these from your computer to the three numbered display positions on the Programmable Refractometer using the built-in USB computer interface. Scales can be loaded and unloaded from your database to your refractometer at any time. Test results can be saved to your computer, graphed and analyzed. Reads samples as small as 0.4 mL with full scale accuracy of 0.1% using CCD scanner ( linear scanned array imaging) technology. Measurement results, unit of measure and sample temperature are all displayed on the large LCD and visual alarms are indicated by a red LED. The programmable refractometers sophisticated microprocessor provides automatic calibration, automatic temperature compensation and automatic shutoff (after 3 minutes). Features one button calibration to distilled water and indicates when the battery should be replaced (5000 readings). Scratch resistant sapphire crystal lens. Comes ready to use with a 9V battery, distilled water, transfer-pipette, cable, AC adapter, software, instructions and a protective case.
