Abbe Refractometers for low refractive index and high refractive index measurements In addition to our standard Abbe Refractometer NAR-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. Another Optional * We can supply Abbe Refractometer with measurement range of "nD 1.7000 to 2.0800" and with Measurement Temperature Range of "0 to 50°C" or "0 to 120°C".
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 NAR-1T and 2T.
