Note: The source material contains a comparison between EC240 / EC250 and HZPD-T503 / HZPD-T503F configurations. This technical sheet treats VIKING-EC250 as the ash-capable configuration because the product URL and comparison section refer to the touch-screen ash version. Final GLP memory capacity, ash range and exact method implementation should be confirmed in the manufacturer-approved specification.

Laboratory use, selection notes and method fit

VIKING-EC250 · practical configuration notes

When VIKING-EC250 is a suitable choice

  • When a bench conductivity meter with 5.0″ touch-screen operation is required.
  • When conductivity, resistivity, TDS, salinity and temperature must be measured in one instrument.
  • When conductivity-ash workflow is needed for sugar, food or process-control applications.
  • When 0.5 grade accuracy and a 4-ring electrode configuration are preferred.
  • When the laboratory requires USB / RS232 output and optional printer support.
  • When traceable measurement storage and endpoint control are important for routine QC.

Configuration and method checks

  • Confirm whether the supplied EC250 configuration is the ash-enabled HZPD-T503F version.
  • Confirm GLP memory capacity as 1000 or 2000 results before publication in tender documents.
  • Confirm the official ash range and calculation method from the manufacturer manual.
  • Select the correct 4-ring electrode and cell constant for the expected conductivity range.
  • Define reference temperature, compensation mode and calibration standards according to the SOP.
  • Check whether pure-water compensation is required for ultra-pure water workflows.

Important measurement considerations

Conductivity measurement depends on electrode cell constant, temperature compensation settings, calibration standard condition, sample matrix, sample temperature and probe cleanliness. The wide conductivity range of VIKING-EC250 makes the instrument suitable for ultra-low to high-conductivity laboratory samples, but method suitability should always be checked against the expected range and acceptance criteria.

For ash-related workflows, the exact conductivity-to-ash method, range, reporting format and acceptance criteria should be confirmed from the official manual or manufacturer-approved method sheet before the instrument is used as a procurement or contractual specification.

Water quality

Routine and advanced checks for conductivity, TDS, salinity, resistivity and temperature in water laboratories.

Food / sugar industry

Conductivity-based ash workflows can support sugar and food laboratories where ash estimation is part of QC.

Ultra-pure water

Pure-water compensation, where confirmed, supports workflows where very low conductivity must be monitored.
