A.KRÜSS Optronic Digital Refractometers T-Model
Versatile and powerful!
Digital laboratory refractometers from A. Krüss Optronic are setting new benchmarks on many counts. An intuitive touchscreen presents a clear overview of all data and functions and the integrated SQL database stores all data and allows external access via a network or standalone PC. The refractive index is a parameter in quantitative or qualitative analysis and quality assurance. Degrees of polymerisation can also often be monitored frequently, quickly and cost-efficiently without turbidity or the colour of the sample affecting measurement precision. There is no longer any elaborate preparation of samples necessary. The sample is simply placed on the measuring prism and the measurement process is started. The flat stainless steel plate is easy to clean and is highly resistant to aggressive substances. As the refractive index depends on the temperature of the sample, the refractometer should be tempered. The DR6000 series is thus available with integrated electronic temperature control by means of a Peltier element. This type of temperature control is faster and more reliable than water bath thermostats. For continuous measurements or series of measurements with many samples and high volumes of samples, devices with flow measurement cells are available. A sample can thus displace the previous one, nonetheless achieving an accurate measurement result without cleaning the measuring prism after every measurement. The DR6000 series of refractometers are robust, low- maintenance and also very quiet - an often underestimated quality for equipment used continuously in a laboratory. An integrated SQL database stores up to 99 user-defined measurement methods and the last 999 measurement values with all associated data. You can select the stored results by means of various filters and export data iXLS- or CSV-format on a USB flash drive, print directly or convert to a PDF document for printing from a PC. By connecting a printer to the RS-232 interface, results can be printed out as soon as they are measured. The refractometer can be connected to a PC or linked to a network via an Ethernet interface. If there is access to the Internet, remote maintenance and fault diagnosis are also possible. Optional user management functionality with three authorisation levels protects the settings from being changed unintentionally. The DR6000 series thus meets all GLP requirements and is best suited for use in FDA-regulated situations. Special KrüssLab software also enables the instrument to be controlled from a PC. This exactly replicates the intuitive touchscreen of your Krüss unit, allowing you to "operate" it directly from the PC. Measured values are copied from the device into the KrüssLab database. You then have permanent access to more than the last 999 results. This data can be accessed even when the Krüss unit is switched off. The refractometers in this series meets the guidelines of ASTM D1218 and D1747.
