Digital Refractometer

The J57-VT High Accuracy Refractometer and J57-VT Wide Range Refractometer are part of the Rudolph Research Product Line. The Rudolph J57-VT High Accuracy and J57 Wide Range refractometers are designed to meet the unique needs of food quality testing where the automatic refractometer is viewed as a quality control (QC) 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. In the food industry, fast, automatic, and accurate Brix readings are required.

Capabilities to meet your Application – Two Models J57-VT High Accuracy & J57-VT Wide Range

Where High Accuracy is critical the J57-VT 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 J57-VT HA are designed to meet the application requirements of the Food and Beverage Industry.

Where Measurement Range is most importance the J57_VT WR Model Refractometer offers an RI Measurement range of 1.3-1.7 and Brix measurement range of 0-100 with Accuracy of ±0.0001 RI and Brix Accuracy of ±0.1. The Rudolph J57-VT WR is an excellent fit for Chemical Industry Laboratories where applications often require a wider RI measurement range.

Automatic Measuring System

Rudolph J57-VT High Accuracy refractometer features a fully automatic measuring system. 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.
