Reproducible results
Automatic, manual or timed endpoint formats with 3 selectable stability criteria allow rapid and accurate measurement value determinations  with reproducible results.
• Linear & non-linear temperature correction
• Selectable reference temperature (20C or 25C)
• Procedure for automatic α -coefficient determination

Professional calibration
• User-definable buffers and standards including their temperature dependence
• Up to 5 calibration points with linear or segmented algorithms
• Multipoint conductivity calibration
• Automatic buffer recognition within the 8 predefined pH buffer groups
• Automatic standard recognition of the 5 predefined conductivity standards
• Entry and display of cell constant

Electrode test
An integrated pH electrode test checks the slope, offset, drift  and response time of your electrodes without changing your current calibration.

Complying with USP/EP standards
SevenMulti™ provides a special mode for measuring conductivity according to USP and EP (United States / European Pharmacopeia) methods.


Features and Benefits

User-friendly operation

The back-lit display shows you all the important information at a glance, even in two-channel operation. Context-sensitive help assists you with every step.

Automation increases efficiency

Efficiency is significantly increased using peripherals such as bar-code readers - not only for high throughput applications.

Security has priority

PIN-protected The operation of the instrument and general system settings such as date and time can be protected through the use of a personal code.
GLP excellenceSevenMulti™ lets you enter up to 12-place sample, user and sensor IDs - you can even use a bar-code reader. Furthermore it features an excellent data management with 1000 GLP measuring points and 400 GLP calibration points.
Calibration reminder This useful function reminds you that a calibration is due after a user-defined period. The instrument can be set to block its use once this period has been exceeded - until the next valid calibration has been performed!
