DIGITAL ABBE REFRACTOMETER	DR-A1
Cat.No.1310

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 %, selective) in digits together with temperature on the display. This refractometer enables anybody to carry out measurement easily without reading of analog graduation. *Dispersive value cannot be measured by this refractometer.
Measurement range: Refractive index(nD) 1.3000 to1.7100 Brix(%) 0.0 to 95.0%(automatic temperature compensation is executed at 5 to 50 oC) Minimum scale: Refractive index(nD) 0.0001 Brix(%) 0.1% Measurement accuracy: Refractive index(nD) +/-0.0002 Brix(%) +/-0.1% Measurement temperature range: 5 to 50 oC Size and weight: Main unit 13x29x31cm, 6.0kg

MULTI-WAVELENGTH ABBE REFRACTOMETER	DR-M2
Cat.No.1410

Refractive index or Abbe number( v d or v e) can be measured at different wavelengths. The DR-M2 digitally displays measurement result of refractive index or Abbe number 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-21(B) (optional).
Measurement range: 1.3000 to1.7100 in refractive index Minimum scale: 0.0001 in refractive index 0.1 in Abbe number Measurement accuracy: +/-0.0002 in refractive index +/-0.1 in Abbe number Measurement temperature range: 5 to 50 oC Size and weight: Refractometer 13x29x31cm, 6.0kg Light source unit 15x33x11cm, 3.0kg

ABBE REFRACTOMETER	1T
Cat.No.1210

The 1T is an Abbe refractometer of standard type, measures refractive indices of liquids and solids quickly and accurately. It is designed to give refractive indices of D line without using a sodium lamp.
Measurement range: Refractive index(nD) 1.3000 to1.7000 Brix(%) 0.0 to 95.0% Minimum scale: Refractive index(nD) 0.001 Brix(%) 0.5% Measurement accuracy: Refractive index(nD) +/-0.0002 Brix(%) +/-0.1% Measurement temperature range: 0 to 50 oC Size and weight: Main unit 13x18x23cm, 3.4kg

ABBE REFRACTOMETER	2T
Cat.No.1220

Designed for use with compounds which require measurement at high temperature.
Measurement range: Refractive index(nD) 1.3000 to 1.7000 Brix(%) 0.0 to 95.0% Minimum scale: Refractive index(nD) 0.001 Brix(%) 0.5% Measurement accuracy: Refractive index(nD) +/-0.0002 Brix(%) +/-0.1% Measurement temperature range: 0 to 120 oC Size and weight: Main unit 12x20x25cm, 5.8kg

ABBE REFRACTOMETER	3T
Cat.No.1230

The type 3T has been developed to give improved measuring accuracy and ease of use. This has been achieved by making fundamental improvements to the optical system, utilising a larger scale, incorporating a high intensity lamp and using a double control knob to give quick and finer control.
Measurement range: Refractive index(nD) 1.30000 to 1.71000 Brix(%) 0.00 to 95.00% Minimum scale: Refractive index(nD) 0.0002 Brix(%) 0.1% Measurement accuracy: Refractive index(nD) +/-0.0001 Brix(%) +/-0.05% Measurement temperature range: 0 to 50 oC Size and weight: Main unit 12x31x34cm, 9.0kg

ABBE REFRACTOMETER	4T
Cat.No.1240

R & D on new materials for modern technologies is being actively conducted in every industry. Many of these materials (especially polymer film and related materials) are of high refractive index-often too high for the existing Abbe refractometers. But these are now covered with the nD1.4700 to 1.8700 range of the type 4T.
Measurement range: Refractive index(nD) 1.4700 to 1.8700 Minimum scale: Refractive index(nD) 0.001 Measurement accuracy: Refractive index(nD) +/-0.0002 Measurement temperature range: 0 to 50 oC (Temperature range available of the circulating water) Size and weight: Main unit 13x18x23cm, 3.4kg

Abbe Refractometers for low refractive index and high refractive index measurements

In addition to our standard Abbe Refractometer type 1T, 2T, 3T, 4T and DR-A1, we can supply the following Abbe models. We shall ask you to use them if the specifications of our standard Abbe Refractometers do not meet your requirements.
Abbe Refractometer 1T-LO(for low refractive index measurement) Cat.No.1217
Measurement range: Refractive index(nD) 1.1500 to 1.4800 Measurement temperature range: 0 to 50 oC

Abbe Refractometer 2T-LO(for high temperature and low refractive index measurement) Cat.No.1227
Measurement range: Refractive index(nD) 1.1500 to 1.4800 Measurement temperature range: 0 to 120 oC

Abbe Refractometer 2T-HI(for high temperature and high refractive index measurement) Cat.No.1228
Measurement range: Refractive index(nD) 1.4700 to 1.8700 Measurement temperature range: 0 to 120 oC

Another option
*We can supply Abbe Refractometer with measurement range of "nD 1.7000 to 2.1000" and with measurement temperature range of "0 to 50^oC" or "0 to 120^oC".
Note:You are requested to convert measured refractive indices to "real refractive indices" (with referring to conversion tables), since the above Abbe Refractometers have the same scales as our standard Abbe Refractometer type 1T and 2T.
