Rudolph Research Analytical J Series refractometers

Rudolph Research Analytical manufactures high-precision refractometers for research and QC applications. The J Series product line includes standard and wide range refractometers. Electronic temperature control is standard on all of the company’s refractometers, eliminating the need for waterbaths - resulting in cost savings and avoidance of possible contamination.

All the J Series refractometers have a light source guaranteed for the life of the instrument, a shallow dish for easy cleaning and differ from the traditional Abbe refractometer, by eliminating the need for prism replacement and easily handling darker samples, all of which make the units easy to use with low running costs.

The latest release, J457, features Smart Measure which checks the sample during measurement and that the prism is clean before and after measurement, thus eliminating some of the more common errors. Other features include a simple touch-screen operation, the ability to split the system to use as a two-piece unit and modern connectivity.
