Product Overview

HI88713-11 Turbidity Calibration Standards provide a simple solution for calibrating and verifying turbidimeters in the 0 to 1000 FNU range and 0.00 to 4000 NTU range. Hanna turbidity calibration standards are made from NIST-traceable primary standard reference materials and are supplied with a certificate of analysis. The certificate of analysis provides the lot number, reference values, and expiration date for traceability when certifying an appropriately calibrated turbidimeter.

• Certificate of analysis supplied

• Standard values of <0.10, 15, 100, 750 FNU and 2000 NTU

• Reusable with long shelf life and good stability

• Turbidity turbidimeters are designed to be routinely standardized using known light-scattering standards. As with all analytical standards or reference materials, turbidity standards should be able to perform the following: provide traceability, demonstrate the accuracy of results, calibrate equipment and methods, monitor user performance, verify tests, and facilitate comparability. Standardization ensures that, when correct procedures are followed, the same analysis performed on the same material will produce mutually consistent results regardless of when it is performed.

• Hanna turbidity standards are prepared from AMCO AEPA-1 material, which is known for highly stable and reliable standardization. AMCO APEA-1 turbidity standards are stable suspensions of cross-linked styrene-divinylbenzene copolymer microbeads in ultrapure water. These beads are chemically inert and maintain chemical equilibrium in aqueous media regardless of concentration. The particle size, uniform shape, and refractive index make these spheres ideal for characterizing light absorption and scattering behavior at 90° in the UV-VIS range. In addition, the spherical shape and size of the beads help prevent accumulation or settling of the standard material. For these reasons, AMCO AEPA-1 standards are very stable.

• These standards are prepared and bottled in a cleanroom facility. They are tested and verified for accuracy and stability and are proven to contain no toxic chemicals or compounds. All prepared standards are compared against a formazin turbidity standard solution. The values obtained and the analysis date are reported on the supplied certificate of analysis.

• HI88713-11 is a set of high-quality turbidity calibration standards that allows users to verify and calibrate turbidimeters in the 0 to 1000 FNU range and 0.00 to 4000 NTU range. The HI88713-11 kit includes five cuvettes with expected readings of <0.10, 15, 100, 750 FNU and 2000 NTU.
