Selection guidance
VIKING-EC400 is chosen where ±0.5 % FS accuracy and resistivity up to 100 MΩ·cm are needed, e.g. for purified and pharmaceutical water, with GLP records and printer output. COLO.Science helps you choose the electrode and standards.
Configuration checklist
- Sample type: drinking, waste, pure or process water, solutions, brines.
- Range: expected conductivity decides the cell constant (k = 0.01 / 0.1 / 1 / 10).
- Calibration: number of points and standards close to the sample value.
- Documentation: memory, GLP records, USB export or printer.
