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-protectedThe 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 reminderThis 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!
