J57WR Bench Automatic Refractometer for Chemical QA

Description

The J57WR Bench Automatic Refractometer from Rudolph Research Analytical is configured for quality assurance and process control in chemical and industrial applications. It distinguishes itself with an exceptionally wide measurement range of 1.30 to 1.70 refractive index, enabling the analysis of diverse materials such as fluorocarbons and aromatic chemicals that fall outside the range of standard instruments. Designed for operator-friendly, high-throughput use, it features a one-button, automatic measurement system with results shown on a backlit LCD, requiring no manual interpretation of shadow lines. The integrated electronic temperature control actively regulates sample temperature between 10°C and 65°C, providing the accuracy of a temperature-controlled instrument without the maintenance demands of an external circulating water bath. This is particularly valuable for chemical samples where standard sucrose-based temperature corrections are ineffective. The device offers a resolution of ±0.0001 RI or ±0.01 BRIX and delivers results in a user-configurable time frame of less than five seconds.
