YSI multimeter data

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: June 27, 2025 | Last Modified: 2017-06-20
A YSI Model 556 multi-parameter instrument was utilized to collect traceable temperature compensated specific conductivity (SC) readings to scale each Onset in-river sonde using manufacturer provided HOBOware® Conductivity Assistant software. The YSI instrument was calibrated each morning using YSI-3161 1000 μS cm−1 standard solution, checked again each night, and checked weekly using YSI-3165 100,000 μS cm−1 standard solution. Daily calibration check precision (n = 42) was 98 ± 2% (mean ± standard deviation), and the weekly high range linearity check precision (n = 9) was 95 ± 4%. This dataset is associated with the following publication: Landis , M., A. Kamal, K. Kovalcik , C. Croghan , G. Norris , and A. Bergdale. The Impact of Commercially Treated Oil and Gas Produced Water Discharges on Bromide Concentrations and Modeled Brominated Trihalomethane Disinfection Byproducts at two Downstream Municipal Drinking Water Plants in the Upper Allegheny River, Pennsylvania, USA. SCIENCE OF THE TOTAL ENVIRONMENT. Elsevier BV, AMSTERDAM, NETHERLANDS, 542(2016): 505-520, (2016).
