Designed for use in a wide range of applications from routine analysis to advanced research, these refractometers are easy-to-use tools for concentration measurements, purity determination and chemical identification. Shadowline detector is sensitive enough to handle demanding samples easily such as inks or grape juice. Automatic temperature compensation corrects readings for temperature variations. Traceability is enhanced with a detailed calibration history record. In addition, up to five calibration points may be set in the AR600 and up to three calibration points may be set in the AR400, each of these points being completely definable. Complete on-screen instructions easily take the user through set-up and calibration.
Refractometers contain a clear, graphical LCD display and full menu operation in English, Spanish, French or German. Up to 14 custom scales may be stored. An on-screen shadowline display provides a graphical display of the shadowline on the Linear Scanned Array image sensor. This allows visual interpretation of the shadowline for detailed sample characterization.
Optional Sample Press and Flow Cell devices help improve precision and ease of use. These accessories provide rapid temperature equilibration between the sample and instrument, and help eliminate evaporation of volatile samples. The Flow Cell, ideal for samples with oils, fats or particulate matter, reduces the effect of non-homogenous samples. The Sample Press is ideal for high content sugar solutions, thick polymers or gels.
