The new digital refractometers in the DR7000 series contain an optical sensor, temperature control, measurement electronics and touch-screen display, all the components needed to reliably measure refractive index, %Brix or concentrations. The Operation is located directly on the device. A separate PC with software is not necessary.
The devices and their firmware guarantee high data security and meet all requirements for FDA-regulated areas (depending on the model), as well as for the European (Ph. Eur.) and American (USP) pharmacopoeia

The advantages of the new digital refractometers at a glance:

Operation: Lightweight - Fast - User-friendly

Capacitive 7.0-inch touch display
Interactive user interface in several languages
Easy-to-understand, menu-guided adjustment
Any number of user profiles possible
Export as print via network/printer or to USB stick
Export also to several password protected network folders
Operation also via keyboard and/or PC mouse
Help and explanations “On Board” for Operation without a manual

Measurement: Almost all samples are measurable

Precise Peltier temperature control and a measured value preview which is updated every second
Automated conversion to any measurement variables/scales
Pre-installed scales: Refractive index, %Brix sucrose, many other scales on request
Up to three scales visible at the same time
Single, interval or continuous measurement
Low sample volume from < 0.3ml
Easy cleaning due to flat measuring recess
Scratch-resistant sapphire prism

Design: Advanced technology for precise measurements

New ventilation concept: ventilation unit is hermetically separated from optics and electronics
Electronics are protected from dust and other environmental influences, making the device low-maintenance
Intelligent waste heat control and ventilation control
Improved sample temperature control for even greater accuracy and measurement consistency
High-tech display with state-of-the-art user management
Option for modular replacement of the flow-through cell
