DR-M4 Abbe Refractometer by Atago U.S.A.
Refractive Index or Abbe number (vd or ve) 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 (Part No.RE-9119) is required. The DR-M2/DR-M4 digitally displays the measurement results of refractive index or Abbe number on the LCD. Measurement can be achieved by matching the boundary line at the intersection point of the cross hairs. These refractometers can be connected to the digital printer.
| Wavelength | 450nm: Refractive Index 1.5219 to 1.9220 589nm: Refractive Index 1.4700 to 1.8700 680nm: Refractive Index 1.4545 to 1.8544 1,100nm: Refractive Index 1.4260 to 1.8259 |
| Minimum Indication | Refractive Index (nD) 0.0001, Abbe number 0.1 |
| Measurement Accuracy | Refractive Index (nD) ±0.0002 (with the attached test piece at 589nm) |
| Wavelength range | From 450 to 1,100nm (with interference filters) (For measurement at wavelengths ranging from 681 to 1,100nm, the near infrared ray viewer (optional) is required.) |
| Measurement temperature range | 5 to 500°C |
| Output terminal | For digital printer, DP-22(B)(optional), Conforming to Centronics standard |
| Power supply | AC100V to 240V, 50/60Hz |
| Power consumption | 160VA |
| Dimensions & Weight | 13×29×31cm, 6.0kg (Refractometer) 15×33×11cm, 3.0kg (Light source unit) |
