Refractometers

A wide range of Refractometers for the Laboratory, Krüss offers six Refractometer options – Digital, Abbe, Process, Digital Handheld and Manual Handheld.

Digital Lab Refractometers

Short measuring times at maximum accuracy

High-precision Digital Lab Refractometer series DR6000 for applications such as mixing-ratio, quality and quantity control, plus determination of purity.

Features & Specifications

With a simple, intuitive touchscreen all results and user management can be operated on the device. The unit incorporates an integrated SQL database, for storing data, and allows for access via a network or standalone PC.

The DR6000 has an integrated Peltier thermostat for efficient temperature control, allowing very short measuring times at maximum accuracy.

Easy cleaning of the probe.

Interface and software package for full GLP compliance.

Four standard models are available in this series, varying according to range, resolution and accuracy

Digital Handheld Refractometers

Krüss offers three models in its DR series of Digital Handheld Refractometers.

The DR301-95 is the largest in this range; it is robust and suitable for everyday usage. Easily connected to a PC, allowing for measurements to be saved and evaluated at a later date, it incorporates the refractive index, sugar and salt scales, with the option to add two other user-defined scales. The DR301-95 offers more flexibility than most handheld devices – it can be easily calibrated, and has an optional temperature compensation feature. Add from the range of accessories the 9V power supply, and it transforms into a small mobile laboratory refractometer.

The smaller DR201-95 is a compact digital handheld refractometer, easy to handle, precise, and fast. Ideal for on-site quality and process control. It has a wide refractive index scale range and a sugar scale. One DR201-95 can often replace several existing instruments. For wine-growing, a special version is available with an Oechsle scale, instead of a sugar scale. Ergonomically designed, the DR201-95 comes complete with a belt pouch.

The DR101-60 is a sturdy, entry level device with an excellent cost/performance ratio, it features the same easy handling and fast measuring results as the two other digital handheld refractometers in this series. It also includes automatic temperature compensation, and is ideal when a wide measurement range is not required.

Abbe Refractometers.

Krüss offers three models in the Abbe refractometer AR series.

The AR2008 is a robust unit, ideal for applications in harsh environments. The refractive index or Brix value and temperature is shown on a LCD display, with a serial interface allowing measured values (date and time) to be transferred to a PC or printer. The AR2008 has automatic temperature compensation, and a thermostat connection of prisms and a built-in light source for the measuring prism. The unit comes complete with a glass calibration plate, contact fluid, screwdriver and a dust hood.

Process Refractometers

Krüss offers two models of Process Refractometers in the PR21 series

The PR21 has been developed for direct insertion into pipes and boilers, for process monitoring, control and separation of products in such industries as chemicals, beverages, food, pulp, paper, and sugar. Installation in a pipeline or tank is simple, as no bypass is necessary. Three interfaces are available for this unit: Analogue 0/4-20 mA, Ethernet, or PROFIBUS.

The PRB21  alternative bypass process refractometer analyses a stream of fluid drawn off the main process run.

Manual Handheld Refractometers.

Krüss offers over twenty models in the HR series of Manual Handheld Refractometers

The HR series of Manual Handheld Refractometers are designed for the determination of mixing ratios, quality and quantity inspection applications within a large range of industries. The HR range has been designed for quick daily usage. It is compact, sturdy and simple to use, measurements are easily read, and is suitable for most applications because of the various scales and functions. For calibration either distilled water or a small calibration plate is employed, depending upon model. The HR is supplied in a case, complete with conversion tables.
