The Rudolph Research Analytical J57 HA Refractometer is designed to meet the unique needs of food quality testing where the automatic refractometer is viewed as a quality control tool rather than a laboratory instrument. A single flat measurement surface, automatic electronic temperature control, and one button measurement capability make it perfect for heavy use food industry applications, where fast, automatic, and accurate Brix readings are required.
Where High Accuracy is critical the J57 HA Model Refractometer offers Accuracy of ±0.00002 RI and Brix Accuracy of ±0.01 with an RI Measurement range of 1.32-1.53 and Brix measurement range of 0-100. The capabilities of J57HA are designed to meet the application requirements of the Food and Beverage Industry.
Rudolph J57 refractometers feature fully automatic measuring systems. The operator simply places the sample on the prism, presses a button and the results are displayed on 7.5cm x 10cm back lit LCD. There are no shadow lines to match and there is no eyepiece requiring operator determination or manual adjustment.
J57 refractometers address temperature fluctuation issues with a built in, maintenance free, electronic temperature control: absolute accuracy regardless of sample type and excellent thermo-stability no matter what the sample or environmental temperatures are. Standard configuration includes sample temperature control to Temperature Control to 20ºC and 25ºC. Variable Temperature control is available with the optional VT model – adds variable temperature control from 20ºC to 65ºC
The J57 HA was designed for the food industry with a BRIX range of 0 – 100% and a Refractive Index range of 1.33 – 1.53 RI. The J57HA has a ±0.01 BRIX and ±0.00002 Refractive Index (RI) accuracy, which matches the accuracy of Rudolph’s best refractometers. Combined with absolute temperature control the J57 HA delivers high accuracy and consistent readings, perfectly designed for rigorous Food Industry applications.
Regardless of the specified instrument accuracy the real world performance will always depend on how well the instrument is cleaned between samples. The J57 refractometers address this issue by providing a very flat easy to clean measurement surface with no corners or crevices that tend to trap sugars, syrups, and other food industry samples.
Includes power supply unit.
