Automatic Refractometer

The AR-1700 Automatic Refractometer from Holmarc is a compact instrument used for measuring the refractive index and brix at the digital, automatic level. The AR-1700 Automatic Refractometer features exceptional accuracy, automatic temperature compensation, a wide reading range, and simple and fast operation. It offers outstanding flexibility to provide accurate readings for a variety of applications. The refractive index measurement is easy, fast and non-destructive and can be used to identify and characterize materials. The sample is placed on the measuring prism and is irradiated by a 589nm (Na D-line) LED. The AR-1700 refractometer features an expanded refractive index reading range of 1.3200 to 1.7000 which enables you to analyze a broad range of samples. The alphanumeric key pad and graphic display provide a means of entering and displaying prompts and data. Regardless of an instrument’s specified accuracy, a refractometer’s real world performance depends on how well the instrument is cleaned between samples. The AR-1700 addresses this issue by providing a very flat, easy to clean measurement surface with no corners or crevices that tend to trap samples causing contamination.
