Original, Irreplaceable, A true classic

 

 

ATAGO's Abbe Refractometers are highly reliable instruments which measure Refractive Index. Compared with other types of refractometers, the Abbe refractometers are capable of measuring liquid and solid samples such as plate glasses, plastic sheets, and other solid films. 

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.

ATAGO's Abbe Refractometers are widely used in a variety of fields; from basic research to product management

Technical Specifications

 

This model features a brighter field of view than its predecessor the DR-A1, making it easier to measure inhomogeneous and/or dark samples.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 (%). This model enables to carry out measurement easily without reading of analog graduation.It can be connected to a printer and computer.Please note that dispersive value cannot be measured by this refractometer.

This is the Abbe Rerfactometer for liquid sample measurement only.
It has the Refractive Index Scale and the BRIX scale, and it comes with D line (589nm) light source. Calibration can be done with distilled water.

The NAR-1T LIQUID is for liquid sample measurement only. This model has the Refractive Index scale and Brix scale, and operates with D line (589nm) light source. Calibration is performed using distilled water.

 This is suitable to measure the Refractive Index Scale and the BRIX scale for liquid and solid samples.

The NAR-1T SOLID Abbe Refractometer was designed for solid sample measurement (this model can also measure liquid samples).This model has the Refractive Index scale and Brix scale, and operates with D line (589nm) light source.

 

Designed for use with compounds that require measurement at high temperatures (up to 120°C). Capable of measuring samples from 5 to 120°C, such as substances with a melting point higher than room temperature, or compounds containing substances with a transition temperature below 120°C. Aside from liquid samples, glass, films, plastics and other solid samples can also be measured.
*Optional accessories: Circulating constant temperature bath (up to 60°C). (Pg. 5)
For a circulating constant temperature bath above 61°C, please purchase separately (not available through ATAGO).

The NAR-3T is the unit with the highest degree of precision and accuracy among the Abbe Refractometers. It was developed to give improved measurement accuracy and ease of use. This was achieved by making fundamental improvements to the optical system and utilizing a larger scale, which allows for a refractive index scale measurements of up to 0.00005. Incorporating a high intensity lamp and using a double control knob gives quick and more accurate control.

Research and Development 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. These can now be measured with the nD 1.4700 to 1.8700 range of the NAR-4T. *Dispersion values cannot be measured with this unit.
