Refractive index or Abbe number (νd or νe) can be measured at different wavelengths ranging from 450 to 1,100nm ( For measurement at wavelengths ranging from 681 to 1.100nm, the Optional Near Infrared Ray Viewer ( RE-9119 ) is required. The DR-M4 displays measurement result of refractive index or Abbe number digitally on the LCD. Measurement can be achieved by matching the boundary line with the intersection point of the cross hairs.
This refractometer is connectable with Digital printer DP-63 (B) (Optional).

Atago DR-M4
Circulating constant temperature bath 60-C4
Circulating constant temperature bath 60-C4
The 60-C4 is an external circulation type constant temperature water tank provided with a thermo-module. The temperature can be set in the range of 10 to 60°C and the unit is perfectly suited for connection with a refractometer.
Digital printer DP-63(B)
Digital printer DP-63(B)
The DP-63(B) is a printer for Multi-wavelength Abbe Refractometer DR-M2, DR-M4, DR-M2/1550 and DR-M4/1550 (Serial No.092101~).
It automatically prints out the number of samples, measurement results, and measured temperature whenever the refractometer completes measurement.
