Tính
năng kỹ thuật:
-
SevenExcellence pH/mV, Conductivity,
Dissolved Oxygen, Ion meter - the ultimate multiparameter benchtop meter. 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) to determine dissolved
oxygen in samples either using digital or polarographic technology, and to
measure the concentration and activity of ions in solution.
-
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
