rightMORE INFORMATION

  • Maximum efficiency with automation

    The DR6000-TF models with flow-through cell enable fully automatic operation in combination with drying unit, peristaltic pump and autosampler. There are four model variants available for the different requirements for accuracy, resolution and measuring range, whereby the same operation and functionality can be accessed.

    • For continuous measurements or series of measurements with high sample volumes
    • For low-viscous to slightly viscous samples
    • With highly accurate internal Peltier temperature control
    • Preinstalled and freely definable scales with conversions based on tables or formulas
    • Chemical-resistant materials such as measurement prism made of sapphire, measuring tray made of stainless steel
    • Intuitive operation via state-of-the-art touchscreen display
    • Complete data recording and backup including audit trail
    • Flexible data export
    • Compliance with global standards and norms

  • Conformity with national and international standards

    A big advantage of normalized measurements is the comparability of the measurement results. Refractometers for specific measuring tasks are recommended as suitable measuring instruments in many international standards and guidelines. The requirements for the measuring devices, such as measuring accuracy and measuring temperature, are dependent on the respective measuring task and defined in each standard. We have compiled for you an overview of all known standards and guidelines, which refer to the refractometry.
