Laboratory use, selection notes and method fit

VIKING-EC400 · practical configuration notes

When VIKING-EC400 is a suitable choice

  • When conductivity, resistivity, TDS, salinity and temperature are required in one benchtop instrument.
  • When the laboratory needs a reliable LCD-based meter without full touchscreen complexity.
  • When 1–3 point calibration and automatic standard recognition are sufficient for the method.
  • When GLP storage, date/time records and stable endpoint detection are important.
  • When USB or RS-232 communication is needed for PC or printer workflows.

Configuration and method checks

  • Confirm the expected conductivity range and sample matrix before quotation.
  • Select the correct EC probe and cell constant for the application.
  • Use suitable standards at 84 µS/cm, 1413 µS/cm or 12.88 mS/cm according to the method range.
  • Define whether linear, pure water or no temperature compensation is required.
  • Review data export, printer and GLP storage requirements before final configuration.

Important measurement considerations

Conductivity measurement depends on electrode cell constant, temperature compensation settings, standard condition, sample matrix, sample temperature and probe cleanliness. VIKING-EC400 covers routine low-to-high conductivity samples, but the selected electrode and method should always match the expected range and laboratory acceptance criteria.

For SOP-compliant workflows, Auto-Hold endpoint locking, GLP storage, date/time logging and USB / RS-232 communication help laboratories document repeatable results and reduce manual recording errors.

Water quality

Routine checks for water quality, process water, wastewater and environmental samples.

Production QC

Conductivity, TDS and salinity monitoring in food, beverage, chemical and pharmaceutical workflows.

Education and research

Repeatable LCD-based operation for teaching laboratories, research projects and method comparison.
