METTLER TOLEDO
3-Channel Meter SevenExcellence™

Modular professional system, which can be equipped with up to 3 of the following modules:
  • pH: for pH / ORP (mV).
  • Cond: conductivity / TDS / salinity / spec. resistance.
  • ION / pH: ion concentration / pH / ORP (mV).
  • DO: dissolved oxygen / BOB / BSC.
  • Wide, high resolution 7áá colour touchscreen (capacitive), very clear and easy to operate.
  • Modularity and flexibility without borders: up to 3 measuring modules can work in parallel, expansion to 2 or 3 channels possible.
  • Universal communication via 2 x USB, ethernet (LAN) and RS232.
  • Plain text user interface in 10 languages with help menu.
  • OneClick™ operation concept: individually configurable functions / workflows start with one click only.
  • Storage for methods.
  • Highest security and GxP support (ID protection, sophisticated user management, limits / alarms, integrated radio clock etc.).
  • Intelligent sensor management (ISM®).
  • Connection of stirrer, sample changer, PC, barcode reader, keyboard, local or network printer possible.
  • Storage up to 20000 data sets (measures, calibrations, methods).
  • Further configurations / expansions see chapter conductivity / oxygen measurement.
  • Compatible to all METTLER TOLEDO electrodes, recommended: ISM® electrodes.
