Abbe Refractometer DR-A1-Plus

This model features a brighter field of view than its predecessor the DR-A1, making it easier to measure inhomogeneous and/or dark samples.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 (%). This model enables to carry out measurement easily without reading of analog graduation.It can be connected to a printer and computer.Please note that dispersive value cannot be measured by this refractometer.
