Available Models
The new DR6000 series of digital refractometers provides highly accurate and repeatable measurement results, offers semi-automatic and fully automatic operation, and is easy to integrate into existing laboratory procedures. A.KRÜSS digital refractometers set new standards in many respects. They provide fast and reliable measurements, intuitive operation, seamless data recording, flexible data export and compliance with global standards. These and many other features ensure user comfort.
Quick reliable measurement
- Small sample volume of about 0.3 ml
- Very short measurement time of approx. 1 s - the fastest polarimeters in the world!
- Measurement with manual input of measurement time or optimized measurement time due to automatic stability recognition
- Reliable temperature compensation
- Highest accuracy over the entire measurement range
- Easy filling and cleaning
- Intuitive operation
- Full documentation of measured values
- Compliance with global standards
Three different model groups are available for different temperature control requirements and automation options:
- DR 6000-T digital refractometers with Peltier temperature control
Powerful and versatile: DR6000-T
As standard, the DR6000-T and DR6000-TF refractometer models are equipped with a Peltier element that controls sample temperature up to 80 °C. Four different models are available to meet different accuracy, resolution and measurement range requirements, so you can access the same operations and functions.
Features:
- Measuring turbid or highly viscous samples
- With highly accurate internal Peltier temperature control
- Pre-installed and freely definable scales with conversions based on tables or formulas
- Chemically resistant materials such as measuring prism made of sapphire, measuring tray made of stainless steel
- Intuitive operation via touch screen
- Full data logging and backup, including audit trail
- Flexible data export
- Compliance with global standards and norms
- Digital refractometers without internal temperature control - DR6000
DR6000 - Specialists for solutions containing sugar
The DR6000 models are particularly suitable for highly accurate measurements of products from the sugar industry. Temperature compensation according to ICUMSA can be used instead of temperature control. Digital models of the DR6000 series without internal Peltier temperature control are particularly suitable for highly accurate measurements of products from the sugar industry. Instead of temperature control, temperature compensation according to ICUMSA can be used. Four model variants are available for different accuracy, resolution and measurement range requirements, so you can access the same operations and functions.
Features:
- Measurement of all samples containing sugar
- Built-in thermostat connections for temperature control with external circulating thermostat
- Pre-installed and freely definable scales with conversions based on tables or formulas
- Chemically resistant materials such as measuring prism made of sapphire, measuring tray made of stainless steel
- Intuitive operation with state-of-the-art touchscreen display
- Full data logging and backup, including audit trail
- Flexible data export
- Compliance with global standards and norms
- DR 6000-TF digital refractometers with automation
Maximum performance through automation
The DR6000-TF flow cell models enable fully automatic operation in combination with a dryer, peristaltic pump and automatic sample feeder. Four model variants are available for different accuracy, resolution and measurement range requirements, so you can access the same operations and functions.
Features:
- For continuous measurements or series of measurements with large sample volume
- For low viscosity to slightly viscous samples
- With highly accurate internal Peltier temperature control
- Pre-installed and freely definable scales with conversions based on tables or formulas
- Chemically resistant materials such as measuring prism made of sapphire, measuring tray made of stainless steel
- Also chemically resistant materials for cables and flow cell
- Controllable with and without external software
- Intuitive operation with state-of-the-art touchscreen display
- Full data logging and backup, including audit trail
- Flexible data export and simple data import with parameter processing via XML interface also possible
- Flexible and method-dependent regulated cleaning procedures
- Compliant with global standards and norms
The DR6000-TF models are ideal for flavor, fragrance and essential oil producers, as well as for the pharmaceutical and beverage industries.
- Routine analysis with high sample throughput
- Quality control of raw and auxiliary materials
- Monitoring the production of intermediate and final products
- Quality and purity control of raw materials and final products
- Determination of sugar concentration in juices and soft drinks
- Determination of alcohol content or extract in beer, condiments, wine or spirits
