Appendix 21. Laboratory Comparison Between YSI EXO And
Appendix 21. Laboratory Comparison between YSI EXO andYSI 6136 Turbidity Sensors using pink clay at the KansasWater Science Center Laboratory, Lawrence, KansasComparison DescriptionStation name: Kansas Water Science Center Lab, Lawrence, Kansas.Equipment: A Yellow Springs Instrument (YSI) EXO water-quality monitor equipped with a YSIEXO turbidity sensor and a YSI 6 series equipped with a YSI 6136 turbidity sensor were deployedin a laboratory turbidity testing apparatus for comparison between the two sensors.(See“Performance Evaluation Tests,” “Laboratory Tests,” p. 7 of main report, for a full description oflaboratory methods.) The Hach model 2100AN laboratory turbidimeter with a flow-through cellwas used as a reference to measure the turbidity in the apparatus bucket every 15 minutesbefore adding more sediment. No datum corrections were applied to either dataset.Testing material and water: Pink clay and deionized water.Calibration standard used: Hach StablCal standards.Laboratory comparison date: February 15, 2017.DatasetsAll data were collected using USGS protocols (U.S. Geological Survey, variously dated) and arepublished in King (2021). Data were edited to remove periods where material was added to thetesting apparatus, leaving the steady-state data for analysis.21.1

Statistical Analyses - YSI EXO and YSI 6136 DataSlope comparisonThe following is a summary of final regression analysis for sensor-measured turbidity from a YSIEXO turbidity sensor and a YSI 6136 turbidity sensor at the Kansas Water Science Centerlaboratory, Lawrence, Kansas, on February 8, 2017; the data used in the final regressions wereaverages of turbidity for each step, each of which had a duration of approximately 15 minutesonce the sensor had stabilized:y 1.26x – 25.44wherey turbidity measured with YSI 6136 turbidity sensor (FNU)x turbidity measured with YSI EXO turbidity sensor (FNU).21.3

The sample mean of treatment YSI 6136 exceeds the sample mean of treatment YSI EXO by an amount that isgreater than would be expected by chance, rejecting the hypothesis that the population mean of treatment YSI EXOis greater than or equal to the population mean of treatment YSI 6136. (P 0.007)Power of performed two-tailed test with alpha 0.050: 0.913Power of performed one-tailed test with alpha 0.050: 0.969Summary of ResultsThere is a strong linear association between measurements made with the two sensors (R 1.00). Relative percentage difference ranged from 14 to 24 percent (median: 18 percent; mean:18 percent). The data passed the Shapiro-Wilk test for normality (P 0.412); therefore, a pairedt-test was performed. The difference between mean values for the YSI EXO and YSI 6136turbidity sensors was statistically significant (P 0.05).Statistical Analyses - YSI EXO and Hach 2100AN DataSlope comparisonThe following is a summary of final regression analysis for sensor-measured turbidity from a YSIEXO turbidity sensor and a Hach 2100AN laboratory turbidimeter at the Kansas Water ScienceCenter laboratory, Lawrence, Kansas, on February 8, 2017; the data used in the final regressionswere averages of turbidity for each step, each of which had a duration of approximately 15minutes once the sensor had stabilized:y 0.50x 110.91wherey turbidity measured with YSI EXO turbidity sensor (FNU)x turbidity measured with Hach 2100AN turbidimeter (FNU).21.5
