Professional User
Management
SevenExcellence™ has an ingenious user management system with four levels from operator to administrator, each with progressively more rights. This allows the assignment of rights to a user that match their experience and authorization level. Therefore the risk of unintentional or unauthorized changes, or deletion of results, is eliminated.
Intelligent Sensor
Management
ISM^® sensors are automatically identified by the instrument, preventing the use of the wrong sensor ID by mistake. Furthermore, calibration data is stored on the sensor and upon connection it is automatically transferred to the instrument for further use.
InLab^® Sensors
Data Security
with LabX^® PC Software
LabX^® adds more functionality to your pH meter such as data and resource management, report creation and ERP/LIMS integration. It also offers regulation support and connects SevenExcellence™ to other laboratory instruments.

FAQ

What can be SevenExcellence™ benchtop meter used for?
SevenExcellence™ stands for convenient, easy-to-understand operation combined with high measurement accuracy and outstanding flexibility. The operation of the instrument with its capacitive touch-screen and large 7 inch display is truly intuitive, reinforced by the availability of menus in 10 languages. The instrument can effectively cope with complex applications and stringent requirements in regulated markets, but it also provides added value for routine measurement tasks in the laboratory. The SevenExcellence™ series comes in different pre-configured models, but each of them can be modularly expanded at any time to add further measurement parameters.

Included in every SevenExcellence™:
uPlace™ sensor holder with the perfectly vertical uPlace™ movement helps you bring your electrode in the position where it works best for your sample. This allows for faster measurements and reduces the risk of the sample vessel tipping over or damaging the sensor.
EasyDirect™ pH activation key for transferring real-time measurement data and archiving your results.

Seven good reasons for SevenExcellence™:
Convenient touch screen operation – easy to learn, quick to work with
Menu guidance in 10 languages - user-friendly operation
Large, well arranged color display – information identifiable at a glance
Modularly expandable at any time – high flexibility
Many peripheral options – highly efficient
Intelligent sensors – peace of mind, eliminating mistakes
Comprehensive service offering, incl. EQPac – high uptime and compliance

METTLER TOLEDO offers pH, ORP, conductivity, ion-selective and dissolved oxygen (DO) sensors. Find the best suited sensor for your application here: www.mt.com/electrode-guide

Improve your electrochemical processes and learn more about possible risks. The GEP Risk Check, a systematic approach to maximize accuracy and repeatability, will point out where you could do better and suggest possible ways to get there.

Is it possible to send data from SevenExcellence™ to a laboratory information system (LIMS)?
For SevenExcellence versions 1.00 / 1.10 / 2.0 / 2.1:
via USB cable from SevenExcellence™ to a PC, where EasyDirect™ pH software is running; a file in user-defined formted can be exported and then imported to LIMS.
via USB cable from SevenExcellence™ to a PC, where any other software converts the incoming data to the desired format and sends it to LIMS
For SevenExcellence™ version 2.2 and up:
SevenExcellence™ 2.2 and later versions additionally provide a remote interface via Ethernet and USB, which can be turned on and configured on the instrument side. The interface allows for processing of complete workflows like deploying a method to the instrument, starting a method on the instrument and collecting all results from the instrument.
For SevenExcellence version 3.0 and up:
SevenExcellence™ 3.0 and later versions can be connected to LabX platform and to setup a fully integrated system which allows bidirectional communication.
Detailed information about installation of remote control for SevenExcellence™ can be supplied to users on demand from local support.

Which printers can be used with SevenExcellence™? Are the cables included?
There are three types of printers that can be used with SevenExcellence™:
Network printers.
A printout similar to a PDF file is created. It is not possible to connect a standard PC printer to SevenExcellence™ directly, only via an Ethernet connection.
USB compact printers (P25, P-56RUE and P-58RUE).
The same information as on a PDF file is printed, but in a more compact format. The mains cable and the USB cable are included in the delivery of the printer.
RS232 compact printer (RS-P25, RS-P26, RS-P28, P-56RUE and P-58RUE).
The same information as on a PDF file is printed, but in a more compact format. The mains cable and RS232 cable are included in the printer delivery. At least for version 1.00, 1.10 and 2.0 of SevenExcellence™ only printers with auto baud rate function are supported. Therefore, RS-P42 or GA42 or similar printers cannot be used. From SevenExcellence™ version 4.0 onwards RS-P42 printers can be used with baud rate deactivated.

Where can I get instructions on how to externally control SevenExcellence™?
SevenExcellence™ versions 1.00 - 2.1:
It is not possible to send any commands to SevenExcellence™ like it used to be possible with SevenMulti™.
SevenExcellence versions 2.2 and higher:
The instrument can be set into a special mode (DCS mode) which allows the user to control it remotely via USB or Ethernet connection. The command set for this is available at your local METTLER TOLEDO support.

How can I get support for LabX® software?
If your LabX^® software is registered, you can become a member of the LabX^® products knowledge base and get access to LabX^® product information for end-user:
