Product Overview

HI88703-11 turbidity calibration standards provide a simple solution for calibrating and verifying turbidity meters in the 0 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 appropriate turbidity meter.

• Certificate of analysis supplied

• Standard values <0.10, 15.0, 100, 750 and 2000 NTU

• Reusable, long shelf life, and good stability

• Turbidity meters are designed for routine standardization 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 the same analysis performed on the same material, when following the correct procedure, 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 90-degree light absorption and scattering

• These standards are prepared and bottled in a cleanroom facility. They are tested and verified for accuracy and stability and are proven to be free of any toxic chemicals or compounds. All prepared standards are compared with formazin turbidity standard solutions. The values obtained and the analysis date are reported on the supplied certificate of analysis.

• HI88703-11 is a set of high-quality turbidity calibration standards that allows users to verify and calibrate turbidity meters in the 0 to 4000 NTU range. The HI88703-11 kit includes five cuvettes with expected readings of <0.10, 15.0, 100, 750 and 2000 NTU. The calibration set is produced in a temperature-controlled environment using NIST-traceable reference materials at our state-of-the-art manufacturing facility.
