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.

Sustainable Fishing in Alaska: Protecting the Salmon Capital of the World through Research
In the far north, the Alaska Peninsula stretches away from the Last Frontier into the Pacific Ocean. A narrow strip of land dotted with freshwater lakes and intruded upon by ocean inlets–this unique region is intimately connected with the surrounding water. Nestled halfway down the peninsula's southern coast are the small villages of Chignik. The area has historically been home to the Aleut people and has been heavily reliant on fishing for centuries. Home to commercial and subsistence fishing today, Chignik continues to rely upon the salmon returns to the surrounding villages, which are supported by scientists working tirelessly to understand and steward these fish populations.

NexSens X3 Data Logger Review
Extreme environments meet extreme design with the NexSens X3 Data Logger . The new logger offers the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library and ultra-low power consumption, all in a waterproof marine-grade housing. The X3 is built to handle harsh weather, floods, high winds and rough seas, and it stands alone; no additional protective housing needed. With an operating temperature that ranges from -40°C to 70°C, the logger can withstand arctic environments and extreme heat. A conformal coating on the internal circuit board isolates it from moisture and humidity.
