Abbe refractometers, NAR-1T series / NAR-2T / NAR-3T

Type NAR-1T-Liquid: 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 achieved using distilled water.

Type NAR-1T Solid: Abbe Refractometer for solid sample measurement (it can also be used to measure liquid samples). It has the Refractive Index Scale and the BRIX scale, and it comes with D-line (589nm) light source.

Type NAR-2T: Designed for use with substances requiring measurement at high temperature.

Type NAR-3T: Developed to give improved measuring accuracy and ease of use. This has been achieved by making fundamental improvements to the optical system, utilizing a larger scale, incorporating a high intensity lamp and using a double control knob to give quick and finer control. With digital thermometer.
