What powers my system and how long will it last?
The system runs on (2) C-batteries and can run continuously for 30 days. The data logger has its own internal battery that can run for up to 6 months.
Can my data logger store memory? If so, for how long?
The data logger has an internal memory that can hold up to 43,000 data points. This allows approximately 11 days with a 1-minute logging interval.
While much of the world has experienced a warmer climate in recent years, the U.S. Southeast has cooled. Scientists want to know why because the answer could reveal keys to improving air quality and understanding climate change.
To study the cooling Southeast, scientists at several institutions have joined forces to conduct the Southern Atmosphere Study (SAS), the largest study on southeastern U.S. air quality since the 1990s. These include the U.S. Environmental Protection Agency, National Center for Atmospheric Research, National Science Foundation, National Oceanic and Atmospheric Administration and the Electric Power Research Institute.
Five air quality studies fall under the SAS umbrella.Read More
NexSens field engineers installed hydrogen sulfide monitoring systems with real-time radio telemetry at several reservoirs in northeast Ohio, where many of the reservoirs have become problem areas for emitting H2S gases as a result of improper restoration of strip-mined land prior to the Surface Mining Control and Reclamation Act of 1977.
Hydrogen sulfide (H2S), a colorless, flammable gas that smells like rotten eggs, is a hazardous substance to both people and the environment. When exposed to even low levels of hydrogen sulfide gas, people can experience eye irritation, a sore throat and cough, shortness of breath, and fluid in the lungs.Read More
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.Read More
