• 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 software's 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 refractometer's 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
