YSI Conductivity Calibrator Solutions are secondary standard solutions for the calibration of conductivity cells together with conductance meters. The solutions are provided in two ranges of accuracy. The YSI 3161, 3163, and 3165 solutions are made to close tolerances and intended primarily for use in laboratory applications where other factors which strongly influence conductivity can also be tightly controlled or accurately measured. The YSI 3160, 3167, 3168, and 3169 solutions are made to less exacting tolerances and are intended mainly for use in field applications where other factors are less subject to close control or measurement.

What is Conductivity?
UPDATE : Fondriest Environmental is offering their expertise in conductivity through their new online knowledge base. This resource provides an updated and comprehensive look at conductivity and why it is important to water quality. To learn more, check out: Conductivity, Salinity and TDS . Salinity and conductivity measure the water's ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. Conductivity measures the water's ability to conduct electricity. It is the opposite of resistance. Pure, distilled water is a poor conductor of electricity.

Restoration, Testing, Research and Education
A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek. As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow. Much of the original property and surrounding land has fallen prey to urban sprawl.

Storms Cause Extended, Elevated Contaminant Concentrations in Urban Streams
Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die. Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn. This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area. “‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters. This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.
