Calibration, optical workflow and field data handling
Zero + 1–3 point calibration
VIKING-TU90P supports zero plus 1–3 point calibration using Formazin standards at 2, 20 and 200 NTU. This keeps the workflow simple for practical 0–200 NTU drinking water, wastewater and field-monitoring applications.
ISO 7027 optical concept
The stable 850 nm LED source and ISO 7027 near-infrared measurement approach support routine turbidity testing where colour-related interference should be reduced and field results must remain comparable.
Portable field workflow
The IP65 housing, AA battery option, AC adapter and carrying case support field sampling, outdoor use and quick verification near the sampling location.

Applications and laboratory value
Drinking water checks
VIKING-TU90P supports routine turbidity checks for drinking water, treated water and field-linked quality verification.
Wastewater and process water
The 0–200 NTU working range supports practical checks in wastewater, effluent and process-water workflows where simple field measurement is needed.
Environmental field sampling
Portable operation, IP65 housing and AA battery power make the instrument suitable for rivers, lakes, surface water and environmental field campaigns.
Food, beverage and education
Simple calibration, TFT display and portable kit format make VIKING-TU90P practical for process checks, QC training and routine laboratory use.
How to choose the correct portable turbidity configuration
When selecting the VIKING-TU90P portable turbidity meter, the expected turbidity range, sample type, field conditions, reporting requirement and calibration standard set should be checked before quotation. Drinking water and treated water applications require careful vial handling and clean measurement surfaces, while wastewater or process samples may require more frequent cleaning and additional replacement vials.
COLO.Science can support the selection of Formazin standards, replacement turbidity vials, batteries, carrying-case kits and field measurement workflow so that the final VIKING-TU90P configuration matches the application and reporting requirement.
VIKING-TU90P portable turbidity meter for 0–200 NTU field water testing
The VIKING-TU90P portable turbidity meter is useful when a laboratory, field team or quality-control user needs a compact instrument for routine turbidity testing within a practical 0–200 NTU range. The combination of ISO 7027 850 nm optics, nephelometric measurement, Formazin calibration, IP65 protection and portable power options supports repeatable work in field and routine laboratory environments.
In practice, turbidity measurement quality depends not only on the meter but also on calibration standard quality, vial cleanliness, correct sample mixing, bubble removal, wiping technique and consistent method execution. VIKING-TU90P provides the portable measurement platform, while COLO.Science can help define the correct calibration and accessory set for the final application.
