The DR-M4 is a digital Refractive Index (nD) Abbe refractometer that is designed for Refractive Index or Abbe number (νd or νe) to be measured at different wavelengths ranging from 450 to 1,100nm, and display on the LCD (for measurement at wavelengths ranging from 681 to 1,100nm, the Optional Near Infrared Ray Viewer RE-9119 is required). Measurement can be achieved by matching the boundary line with the intersection point of the cross hairs. This refractometer is connectable with optional digital printer DP-63 (B).
