Abbe refractometer DR-A1-Plus

digitallaboratorybenchtop

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. Range - Refractive index (nD) : 1.3000 to 1.7100 Brix : 0.0 to 100.0% (Automatic Temperature Compensation at 5 to 50°C) Minimum Scale - Refractive index(nD) : 0.0001 Brix : 0.1% Accuracy - Refractive index (nD) : ±0.0002 Brix : ±0.1% Measurement Temp. - 5 to 50°C Light source - LED (Approximating to wavelength of D-Line) Output - (1) Digital Printer DP-AD(C) (Optional) is used. (2) Communication syste : RS-232C Dimensions & Weight - 13×29×31cm, 6.0kg (Refractometer)
