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.

In warmer climates like Texas, high reservoir evaporation rates can lead to declines in water level and water availability during droughts, making monitoring essential in order to ensure water security during times of scarcity. 
 
According to the Texas Water Development Board (TWDB), evaporation rates in Texas were previously based on data collected from a sparse network of Class A evaporation stations, dating back to the 1960s. These pans were stationed near reservoirs and still remain a widely accepted standardized approach to measuring evaporation rates on land. 
 
Monthly pan-to-lake coefficients were developed in the 1980s to connect the data collected from the pans to known lake conditions, extrapolating evaporation rates of the lakes using the pan data.
