Test solutions for the determination of photometric accuracy and linearity

NANOCONTROL NANOCHECK 2.0 is a secondary standard for the control of inspection, measuring and test equipment in accordance to ISO 9001.

The test solutions have been checked in a reference photometer monitored with NIST-traceable standards. The results are documented.

The photometric accuracy is checked with 2 types of colored solutions. Both solutions are included in three different concentrations to check the photometric linearity.

NANOCONTROL NANOCHECK 2.0 fullfils the requirements of analytical quality control mentioned in the DWA-advisory leaflet A 704 (Operational Methods for the Self-Monitoring of Wastewater Systems).
