YSI 6560 Temperature/Conductivity Sensor
Features
- Titanium-encased temperature sensor
- Measures conductivity via 4 pure-nickel electrodes
- Field-replaceable
- Expedited repair and warranty service
- Lifetime technical support
- More
Overview
Included with virtually every 6-Series sonde, the YSI 6560 provides reliable temperature and conductivity readings. The YSI 6560 Temperature/Conductivity Sensor is extremely linear and accurate within its 0.5% accuracy specification when calibrated anywhere in the range.
Temperature
YSI utilizes a high-precision thermistor 2252 ohms at 25 C (+/-1%) for temperature measurement. Resistance changes with temperature, and the 6-Series sondes convert resistance into C, F, or K automatically. Best of all, the temperature sensor is calibration and maintenance-free.
Conductivity
Four pure-nickel electrodes allow the YSI 6560 to accurately determine the conductivity of a sample. Along with conductivity, the YSI 6-series sonde can calculate specific conductance, salinity, resistivity and total dissolved solids.
- Range: -5 to +50 C
- Resolution: 0.01 C
- Accuracy: +/-0.15 C
- Warranty: 1 year

Cooling water from Northeast U.S. power plants keeps rivers warmer
Rivers are a vital cooling source for power plants, but high-temperature water returned to rivers from the plants may detrimentally heat rivers and change aquatic ecosystems, according to a recent study. 
 Scientists from the University of New Hampshire and the City College of New York gathered federal data on power plants and river systems and linked up river flow and heat transfer models to figure out just how hot rivers get in the northeastern U.S. 
 They found that about one third of heat generated in thermoelectric power plants in the Northeast is drained into rivers via used cooling water. Just more than a third of the total heat generated at plants in the Northeast is converted directly into electricity for consumer use.

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.

Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. 
 
[caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.
