The Rudolph J157 Digital Refractometer offers high performance and a range of features to suit many demanding applications in laboratories and harsh industrial environments. Rudolph Research Analytical, working together with refractometer (Refraktometer) users from various countries and disciplines, has developed the J157 series of Digital Refractometers. The Rudolph J157 benchtop refractometer line combines the features, measurement range, and accuracy that meet the most demanding applications both in and out of the laboratory and shares many features with the Rudolph Research Refractometer Product Line. J157 PLUS HA Digital Refractometer perfect for High Accuracy measurements in the Sugar, Food & Beverage Industry The Rudolph J157HA Digital Refractometer offers High Accuracy of RI ±0.00002, BRIX ±0.01 with a measurement range of RI 1.32 – 1.53, BRIX 0 – 100. Most importantly, this makes the J157HA an excellent choice for quality control of food and beverage products. Digital Refractometer – J157 PLUS WR ideal for the Chemical Industry. With a measurement range of RI 1.29 – 1.66 and BRIX 0 – 100 the Rudolph J157WR offer the versatility needed for Chemical plants where the chemicals are primarily non-water based. In addition, the J157WR offers accuracy of ±0.0001 RI and ±0.1 BRIX which is in excess of the accuracy required in most Chemical Plants. J157-633 for Biotechnology and Bioengineering Research A Biotechnology and Bioengineering refractometer designed specifically for measuring materials in the Optical Waveguide Lightmode Spectroscopy (OWLS) system thus capable of measuring the effective refractive index of a thin layer above an Si(Ti)O2 waveguide surface.
