Digital refractometer DR7200-P

When accuracy counts: DR7200-P digital refractometer with audit trail

The laboratory refractometer of the DR7000 series stands for precise digital measurement technology at the highest level. the devices are developed for the reliable determination of refractive index, %Brix and other concentrations in liquid samples.

With its high‑end feature set – comprising an optical CCD sensor, Peltier temperature control, powerful measurement and evaluation electronics, and an intuitive touch display – the laboratory refractometer brings together all components required for reproducible and stable measurement results. Operation is carried out entirely directly on the device; an external PC or additional software is not required. Almost all samples are measurable.

Depending on the model, the firmware of the DR7000 series measuring devices meets all requirements for FDA-regulated areas as well as the requirements of the European (Ph. Eur.) and American (USP) Pharmacopoeia. The DR7200-P and DR7400-P models also comply with the strict guidelines of 21 CFR Part 11 and EU Annex 11 making them ideal for use in quality-critical, regulated environments.

Advantages

Digital refractometer developed for efficient work

• Capacitive 7-inch touch display for a brilliant display and precise input
• Intuitive, interactive user interface – optionally in several languages
• Operation via keyboard and/or PC mouse
• Menu-guided, easy-to-understand adjustment – safe, fast and accurate
• Any number of user profiles possible – clear rights and clear assignment of users
• Export to password-protected network folder (PDF, A-format, CSV) or USB stick
• With help and explanations “on board” for operation without a manual

Measurement: Perfection in detail – precision in results

• Pre-installed scales: Refractive index, %Brix sucrose; customized scales are available
• Precise Peltier temperature control and measured value preview updated every second.
• With single, interval or continuous measurement (small sample volume of < 0.3ml)
• Automated conversion to any measurement variables and scales. Up to three scales are visible simultaneously during the measuring process

Digital refractometers with innovative assistance systems

• TempGate^®
  The set sample temperature control is continuously monitored by the TempGate® functionality. An LED ring around the sample well indicates that the digital refractometer is ready to measure.

• Measurement Stability Check – MSC
  This feature can be used to check the stability of the measured value during an ongoing measurement. Only values that meet the set stability criteria are saved.

• Dynamic Temperature Control – DTC
  With this new function, samples are tempered fully automatically and homogeneously. The desired accuracy of temperature control can be set precisely. With DTC, temperature control and measurement periods are optimally adapted to the sample and reduced to a minimum.

Digital refractometer with powerful measuring functions

• Large temperature control range: 10°-60°C
• Large measurement range: nD1,3000-1,5800; 0-95%Brix
• User accounts: >10000
• Methods: >1000
• Measured data storage > 1 000 000

Sophisticated technology for maximum reliability

• The ventilation unit is hermetically separated from the optics and electrons. This protects the digital refractometer from dust and other environmental influences and ensures long-term, low-maintenance operation
• Low-noise, intelligent waste heat control and ventilation control. Device volume <10 dB (temperature control range 15°C-30°C)
• Modular interchangeable flow-through cell with flat measuring trough for quick cleaning

Reproducible & tamper-proof data with audit trail

The DR7200-P laboratory refractometer complies with the requirements of 21 CFR Part 11 and EU Annex 11:

• Complete traceability: Traceable & reproducible generation of electronically generated measured values.
• Tamper-proof storage: Electronics data must be stored permanently, securely and unalterably.
• Data integrity & authorization levels: Different levels of access rights so that only authorized persons can create, check or export Electronics data.
• Data export: Electronics data and measured values can be exported completely and securely.
• Unchangeable audit trail: Each action is clearly documented by a non-editable, non-deletable audit trail.
• Legally valid electronic signatures
