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.
