Atago 1414 DR-M4 Multi-Wavelength Abbe Refractometer.
Refractive index: 1.5164 to 1.9164 (Wavelength 450nm)
Refractive index: 1.4700 to 1.8700 (Wavelength 589nm)
Refractive index: 1.4558 to 1.8557 (Wavelength 680nm)
Refractive index: 1.4304 to 1.8303 (Wavelength 1100nm)
Minimum Indication: 0.0001 (Refractive Index)
Minimum Indication: 0.1 (Abbe number)
Measurement Accuracy ±0.0002 (refractive index with the test piece at 589nm)
Refractive index or Abbe number (?d or ?e) can be measured at different wavelengths ranging from 450 to 1100nm. (For measurement at wavelengths ranging from 681 to 1100nm, the Optional Near Infrared Ray Viewer (Part# RE-9115) is required).
The DR-M4 displays the 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 the optional digital printer (Part# D-21(A)).
Power: 100-240VAC, 50/60Hz.
Includes: Allen wrench, test piece (refractive index point), monobromonaphthalene (4ml), methylene iodide containing sulfur solution (4ml), lighting glass, interference filters (589nm and 546nm) 1 each, tube bands (10pcs), spare bulb, and owner's manual.
