500 FTU Turbidity Calibration Standard - HI93703-05

The HI93703-05 500 FTU Turbidity Calibration Standards provide a simple solution to calibrating and validating the HI93703 turbidity meter that has a 0 to 1000 FTU range. Hanna turbidity calibration standards are prepared from NIST traceable primary standard reference materials and come supplied with a certificate of analysis. The certificate of analysis provides the lot number, reference values, and expiration date for traceability when certifying the appropriate turbidity meter.

  • Supplied with Certificate of Analysis

  • AMCO AEPA-1 primary turbidity standard
  • Reusable with long shelf life stability


The HI93703 ISO compliant 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.

Hanna turbidity standards are prepared from AMCO AEPA-1 materials that are known for being highly stable and reliable for standardization. AMCO AEPA-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.

This standard is prepared and bottled in a clean room facility. It is tested and validated for accuracy and stability, and certified as free from any toxic chemicals or compounds. All prepared standards are compared to formazin turbidity standard solutions. The values obtained and the date of analysis are reported on the supplied certifcate of analysis.

HI93703-05 is a high quality turbidity calibration standard that allows users to validate and calibrate the HI93703 turbidity meter that has a 0 to 1000 FTU range. HI93703-05 includes one standard solution with an expected reading of 500 FTU. The calibration standard is produced in our state-of-the-art manufacturing facility using NIST traceable reference materials in a temperature controlled environment.
