Basic QA/QC workflows
The instrument can support basic quality checks where a compact, easy-to-use pH/mV meter is sufficient for routine control.
How to choose the correct VIKING-PH110 configuration
When selecting a portable pH meter, the laboratory should define the sample type, expected pH range, calibration method, electrode configuration and whether the instrument will be used mainly in the laboratory, in the field or in both environments. VIKING-PH110 is suitable when the user requires a practical pH/mV meter with simple NIST calibration, manual temperature compensation and IP65 protection.
Before quotation, COLO.Science recommends confirming whether the standard PRO6135 pH composite electrode is suitable for the sample matrix and whether the optional carrying case should be added as a separate commercial item.
VIKING-PH110 as a compact portable pH meter for everyday measurement
VIKING-PH110 Portable pH Meter is useful when a laboratory, school or field team needs a simple and reliable instrument for routine pH and mV measurements. Instead of a complex multiparameter instrument, VIKING-PH110 focuses on the core functions needed for everyday pH work: clear display, easy calibration, stable reading indication, rugged housing and rechargeable battery operation.
The combination of 0.01 pH resolution, ±0.02 pH accuracy, 1–2 point NIST calibration, manual temperature compensation and IP65 protection makes VIKING-PH110 suitable for educational laboratories, field water quality checks, environmental sampling and basic QA/QC control. The optional carrying case can be added when transport, storage and mobile work are important, but it should be quoted separately.
Configuration notice — carrying case is optional
VIKING-PH110 is supplied with the listed electrode and accessories according to the confirmed offer. The carrying case shown in the image is an optional accessory and is not included in the standard product price unless explicitly confirmed in the quotation.
Available configurations, compatible electrodes and accessories should be confirmed before ordering.
