VIKING-EC250 is a professional touch-screen laboratory conductivity meter for routine and advanced water-analysis workflows, including conductivity, resistivity, TDS, salinity and temperature measurement.
The EC250 configuration is positioned for laboratories requiring 0.5 grade accuracy, a 5.0″ color touch screen, a standard 4-ring conductivity electrode, USB / RS232 output and conductivity-based ash workflows for application areas such as sugar, water quality and process-control laboratories.
Broad EC, resistivity, TDS, salinity and temperature coverage supports routine and method-driven water analysis.
Suitable for laboratories that use conductivity-based ash determination, especially where sugar-industry methods are required.
GLP-style database, endpoint control and digital output support repeatable and auditable measurement workflows.

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.
Routine and advanced checks for conductivity, TDS, salinity, resistivity and temperature in water laboratories.
Conductivity-based ash workflows can support sugar and food laboratories where ash estimation is part of QC.
Pure-water compensation, where confirmed, supports workflows where very low conductivity must be monitored.
COLO.Science can support selection of conductivity meters, 4-ring electrodes, calibration standards and accessories for water quality, food / sugar industry, QC and routine laboratory measurement.
