Abbe Refractometer DR-A1
By very simple operation that needs only to set the boundary line of refraction at the cross hairs, this refractometer directly indicates a measured value (in refractive index or Brix (%), selective) in digits together with temperature on the display. 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-63 (C) Digital Printer (sold separately) or transmitted to a computer.
* Dispersive value cannot be measured by this refractometer.
