These standards provide a simple solution to calibrating and validating turbidity meters that have a 0 to 1000 NTU range.
A high quality set of turbidity calibration standards that allows users to validate and calibrate turbidity meters that have a 0 to 1000 NTU range.
The calibration set includes four cuvettes with expected readings of <0.10, 15.0, 100, and 750 NTU.
The calibration set is produced in a state-of-the-art manufacturing facility using NIST traceable reference materials in a temperature controlled environment.
HI98703-11: Turbidity Calibration Standards
The nephelometric turbidity meter is designed to be routinely standardized with a known light scattering standard. As with all analytical standards or reference materials, a turbidity standard should be able to perform the following: provide traceability, demonstrate the accuracy of results, calibrate the equipment and methodology, monitor user performance, validate tests, and facilitate comparability. Standardization ensures that when the correct procedures have been followed, the same analysis of the same materials will produce results that agree with each other whenever they are performed.
This turbidity standard is prepared from AMCO AEPA-1 materials that are known for being highly stable and reliable for standardization. AMCO APEA-1 turbidity standards are a stabilized suspension of cross linked styrene divinylbenzene copolymer microbeads in ultrapure water. These beads are chemically inert and keep their chemical balance in a water medium regardless of concentration. Particle size, uniform shape, and refractive index make these spheres ideal to characterize light absorption and scatter for 90° behavior in the UV-VIS range. In addition, the bead’s spherical shape and size helps prevent the accumulation or precipitation of the standard. For these reasons, the AMCO AEPA-1 standards are very stable.
