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
