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 the measured value 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 temperature controls 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.

CONFORMITY WITH STANDARDS & DIRECTIVES

• Pharmacopoeias (EU / USP / JP / BP)
• ASTM / DIM / ICUMSA / NIST / OIML
• GAMP / GMP

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
