Specification of Abbe Refractometer Digital DR-A1
Refractometer
Abbe Refractometer Digital 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.
* Dispersive value cannot be measured by this refractometer.
