YSI turbidity solutions calibrate your instruments for maximum accuracy. Extremely accurate and stable solutions.
We recommend that YSI-certified polymer-based standards are used for best results.
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.
Each turbidity standard comes in a 1 gallon (plastic) container.
608000: Calibration value of 0 FNU for all YSI sensors
607200: Calibration value of 12.4 FNU for ProDSS and EXO sensors, calibration value of 12.7 for YSI 6136 sensor
607300: Calibration value of 124 FNU for ProDSS and EXO sensors, calibration value of 126 for YSI 6136 sensor
607400: Calibration value of 1010 FNU for ProDSS and EXO sensors, calibration value of 1000 for YSI 6136 sensor
* YSI turbidity standards are no longer supported for 6026 sensors
