Applications and laboratory value
Water-quality laboratories
VIKING-M310FA supports routine measurement of pH, conductivity, TDS, salinity, resistivity, ISE and temperature in drinking water, wastewater, surface water and process water.
Environmental monitoring
IP65 protection, rechargeable power and a carrying case support mobile sampling, outdoor inspections and measurements at different field points.
ISE and ion analysis
The ISE module supports common ions and user-defined methods, making the analyzer useful for laboratories that need concentration reporting in ppm, ppb, mg/L, μg/L or molar units.
Industrial QA/QC
Multi-parameter testing reduces the need for several separate instruments during routine checks of process water, rinse water and inspection points in production facilities.
How to select the right electrodes and configuration
When selecting the VIKING-M310FA portable multi-parameter water analyzer, the final configuration should be matched to sample type, required parameters, expected conductivity range, pH range, ISE method, temperature conditions and reporting requirements. Routine water-quality work may require a robust pH electrode and conductivity probe, while ion-selective electrode applications require the correct ISE electrode, ionic strength adjustment procedure and calibration workflow.
COLO.Science can support the selection of pH electrodes, conductivity electrodes, ISE electrodes, buffer solutions, EC standards, electrode storage solutions, carrying-case configuration and accessories so the supplied analyzer matches the application and the official quotation.
