Digital refractometers without internal temperature control
Refractometer DR6200 with temperature compensation - temperature control possible with thermostat
Refractometer DR6000 with circulating themostat PT80
DR6000 - Specialists for sugar containing solutions
The DR6000 models are especially suited for highly accurate measurements of products from the sugar industry. Instead of temperature control, the temperature compensation according to ICUMSA can be used. The digital refractometer models DR6000 without internal Peltier temperature control are especially suited for highly accurate measurements of products from the sugar industry. Instead of the temperature control, you can use the temperature compensation according to ICUMSA. There are four model variants available for the different requirements on accuracy, resolution and measuring range, whereby the same operation and functionality can be accessed.
- Measuring all sugar containing samples
- Built-in thermostat connections for temperature control with external circulating thermostat
- Preinstalled and freely definable scales with conversions bases 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 touch-screen display
- Complete data recording and backup including audit trail
- Flexible data export
- Compliance with global standards and norms
The refractometers of the DR6000 models are the ideal solution for the sugar industry
- Determination of the sugar concentration in semi-finished products and end products
- Determination of the solids content in solutions
- Determination of the purity in combination with a polarimeter

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.

All samples are measurable
From bright to dark, from basic to acidic, from a low to a high viscosity – for our refractometers almost all samples are measurable. A high-quality optics, intelligent evaluation logarithms and a powerful LED enable the measurement of particularly challenging samples. These include z. For example, non-homogeneous samples such as fruit juices containing pulp, opaque samples such as heavy oils or emulsions that are common in cosmetics. Aggressive acids and bases can be easily measured using a chemical-resistant stainless steel measuring tray and a sapphire prism. Even foils and solids can be measured by using a high-refractive contact liquid.
In order to serve the existing variety of samples and the wide range of applications, we offer a wide range of different refractometers. For the selection of the suitable refractometer, it is helpful to define the required measuring range.
In the following table we have compiled an overview of typical samples from our customers and sorted them by refractive index. Most samples were measured at standard measurement conditions (20 ° C, λ = 589 nm), deviations are indicated. The measurements given are not specifications.
