The Extech Conductivity/TDS Meter features a large 1,000 count LCD display that simultaneously measures conductivity and temperature. Units of measure include μS/cm, mS/cm, ppm, ppt, °F, and °C. The waterproof meter includes adjustable automatic temperature compensation for the highest accuracy of water quality testing.


Model EC100 measures conductivity and temperature with simultaneous readout display, and has two ranges for conductivity with one point calibration per range. Model EC150 features an adjustable conductivity to TDS ration factor from 0.4 to 1.0 that conveniently calculates the TDS value. The meter has two ranges for conductivity and TDS with one point calibration per range.

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.

Volunteer Water Quality Monitoring Networks at the Heart of Citizen Science Movement

Lately, citizen science initiatives have been getting noticed by laypeople and mainstream media outlets. As everyday people become aware of ways they can get involved in actual scientific research, more of them are doing so—especially teachers and parents working with children. But this citizen science wave isn't actually a new thing. It has been growing outward from its core in volunteer water quality monitoring networks for years. Around the country, volunteers have been quietly monitoring the water quality in lakes, streams, rivers, marshes, and other surface waterways for decades. These highly successful programs have been supporting better water quality in communities across America, and in doing so have also formed the heart of the modern citizen science movement.

US Steel Dumping Chromium: Citizens Fighting for Lake Michigan, and Drinkable Water

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.
