This refractometer enables anybody to carry out measurement easily without reading of analog graduation. The DR-A1 Digital Abbe Refractometer can now be connected to a printer and computer. Individual measurements and their average values as well as temperature readings can be printed to a DP-22 (C) Digital Printer (sold separately) or transmitted to a computer. * Dispersive value cannot be measured by this refractometer. Model DR-A1 Cat.No. 1310 Measurement range Refractive index (nD) 1.3000 to 1.7100 Brix 0.0 to 95.0% ( Automatic Temperature Compensation is executed at 5 to 50°C ) Minimum Indication Refractive index (nD) 0.0001 Brix 0.1% Measurement Accuracy Refractive index (nD) ±0.0002 Brix ±0.1% Measurement Temperature Range 5 to 50°C (at unit of 0.1°C) Indication Refractive index ( nD ) or Brix ( % ) and temperature ( °C ) Power Supply With AC adapter ( 100 to 240V ( 50/60Hz ) AC input ) Power Consumption 16VA Output Terminals (1) Digital Printer DP-22(C) (Optional) is used.
