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.

Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.

Real-time wave data supports accurate weather prediction, safe and efficient maritime operations, and provides valuable safety and operating condition information for recreation and commercial fishing. Understanding wave dynamics also helps with the design of protective coastal structures like seawalls, breakwaters, and jetties. It also supports better prediction of their impact on sediment transport and coastal geomorphology. Wave data is a key factor in qualifying and designing offshore wind farms and harnessing kinetic energy for electrical generation. It helps with the understanding of ocean-atmosphere interactions and contributes to studies of sea-level rise and climate change impacts.
