Overview
The Extech ExStick Conductivity/TDS/Salinity Meter features a high-accuracy multi-range sensor that measures four parameters: conductivity, TDS, salinity, and temperature. The autoranging meter offers 3 ranges of measurements from tap water to wastewater and any aqueous solution. The units of measure include μS/cm, mS/cm, ppm, ppt, mg/L, and g/L.
Data Potential
Adjustable conductivity to TDS ratio is from 0.4 to 1.0 to conveniently calculate the TDS value. The large 2000-count digital display simultaneously displays conductivity, TDS, salinity, and temperature, and uses an analog bar graph to indicate sample trends. The internal memory stores up to 25 labeled readings for easy recall. The conductivity module is easy to replace, and the self-calibration function activates when the meter powers on. Other meter functions include data hold, power off, and low battery indication.

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.

Cal Poly, San Luis Obispo Manages Monitoring Efforts in Morro Bay
California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

Green Water in Green Bay: Using Data Buoys to Monitor the Southern Bay
While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.
