Digital refractometer DR7200-P with audit trail functionality (up to 3 years manufacturer warranty)
The DR7000 series devices are digital refractometers designed for measuring refractive index, %Brix or other concentrations in liquid samples. With an optical CCD sensor, Peltiertemperature control, measurement electronics, evaluation electronics and touch display, the devices contain all the components needed to carry out measurements reliably. The Operation is located directly on the device. A separate PC with software is not necessary.
The devices and their firmware meet all requirements for FDA-regulated areas (depending on the model), as well as for the European (Ph. Eur.) and American (USP) pharmacopoeia. The DR7200-P and DR7400-P models meet the requirements of CFR 21 Part 11.

KRÜSS - ASSISTANCE SYSTEMS
- KRÜSS – TempGate©
The set sample temperature control is continuously monitored by the TempGate functionality. An LED ring around the sample well indicates that the DR7000 is ready to measure.
- KRÜSS – MEASUREMENT STABILITY CHECK (MSC)
This function can be used to check the stability of measured values during an ongoing measurement. This means that only measured values that meet the set stability criteria are saved in the results memory.
- KRÜSS – DYNAMIC TEMPERATURE CONTROL (DTC)
The DR7000 controls the temperature of samples fully automatically and homogeneously. With the Dynamic Temperature Control – DTC – function, the desired accuracy of temperature control can be selected. This allows the required temperature control and measurement period to be adapted to individual samples and thus reduced to a minimum.
DATA INTEGRITY
- Tamper-proof measured data and export data (PDF/A)
- Measured value preview during measured value stabilization
- Multi-level user management
- Extensive password settings
- Configurable device interfaces
- Simple integration into existing networks is possible with the DHCP client
