NAR-3T (ABBE Refractometer)

The NAR-3T Abbe refractometer has been developed to improve 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 more refined control.

Available in numerous measurement ranges to suit the needs of any application
Combination Brix and refractive index scales
Capable of measuring solid samples
Capable of measuring Abbe numbers
