SevenExcellence pH/mV, Conductivity, Dissolved Oxygen meter - providing maximum flexibility, regardless of your applicative need. This triple channel instrument allows you to measure pH/mV, rel. mV/ORP, a large variety of conductivity-based measurements (TDS, salinity, resisitivity, conductivity ash) as well as a means to determine dissolved oxygen in samples either using digital or polarographic technology.

 
  • Professional calibration support, incl. automatic calibration with Rondolino sample changer
  • Large 7 inch color display and intuitive menu guidance in 10 languages
  • Flexible method concept for high reproducibility and security
  • Extra security thanks to sophisticated user management and Intelligent Sensor Management (ISM®)
  • Integrated interfaces (USB, RS232 and Ethernet) for data exchange
  • Comprehensive service package including IQ/OQ/PQ
