Calibration, ISE methods and GLP data management
pH and EC calibration
VIKING-M300A supports up to 5-point pH calibration and up to 3-point conductivity calibration.
Standard recognition, selectable buffer groups, cell constant settings and reference temperature options help laboratories adapt the instrument to internal measurement procedures.
ISE ion analysis
ISE functions support concentration units such as mol/L, mmol/L, mg/L, μg/L, ppm and ppb.
Built-in methods for F-, Cl-, I-, NO3-, NH4+, K+, Na+, Ca2+ and other ions simplify routine ion-selective workflows.
GLP and communication
GLP-compliant data storage, 500 data sets per parameter, USB communication and RS-232 printer output support structured recording,
transfer and documentation of measurement results in laboratory and quality-control processes.
Benchtop multiparameter analyzer for daily laboratory workflows
Benchtop multiparameter analyzer VIKING-M300A is useful when laboratories need to measure several electrochemical parameters every day
without operating multiple separate instruments. One platform for pH, EC, ISE, mV, pX, TDS, salinity, resistivity and temperature helps organize the bench,
reduce instrument complexity and simplify user training.
In water quality testing, measurement reliability depends on calibration quality, electrode condition, temperature compensation, sample preparation and stable endpoint detection.
VIKING-M300A supports Auto Read, Timed Read and Continuous Read operation, Auto-Hold endpoint locking and GLP-compliant data storage for traceable measurement workflows.
When configuring the instrument, laboratories should define the required pH electrode, conductivity cell, ISE electrodes, temperature probe,
calibration standards and expected sample range. COLO.Science can help match the analyzer, electrodes and accessories to the real laboratory method.
