Turbidity Standards
| •YSI's polymer-based standards are prepared and labeled so they are traceable to the EPA's primary standard, Formazin •Polymer standards from other vendors may not be properly adjusted to meet YSI's traceability requirements •For example: A 20 NTU labeled bottle from company x will actually read 25 NTU using a properly calibrated YSI 6136 turbidity sensor. |
