The Extech Wireless Remote AC Circuit Identifier combines non-contact voltage and light detection with radio frequency transmission technology.
The Extech Wireless Remote AC Circuit Identifier enables a single user to identify mid-run wires and to find the breaker that powerrs a circuit or light fixture without having to connect directly to the wires in the cable. The meter combines non-contact voltage detection with wirelss signals to monitor and remotely report the presence of voltage on a wire.
Clamped onto a live wire, the transmitter signals the user at the breaker panel with LED and audible alerts on the receiver at up to a 100 meter range. The alerts stop when the correct circuit breaker is switched and work can be performed safely. The identifier eliminates the need for an assistant or back-and-forth trips to confirm that the correct circuit is powered down. This tool is ideal for electricians, plumbers, general contractors, kitchen and bath remodelers, and lighting installers.

Dr. Charley Liberko of Cornell College's Department of Chemistry has an idea he's working to bring to fruition.
“Imagine a remote village in an underdeveloped country whose only source of water is a stream contaminated with toxic levels of metal ions such as cadmium and nickel,” states Dr. Liberko. “The villagers take locally available woody plant material, soak it in potash, and heat it up for several days until the wood partially decomposes. They then filter their water through this material to remove the metal ions. When they are done with it, they put the material in a clay pot and heat it up even hotter until the organic matter decomposes completely, leaving the metal ion salts as a residue, safely in the clay pot.Read More
Sometimes scientists have to make an extraordinary effort to study the questions that concern them. In fact, they may even need to design and build labs to their specifications. This was the case with the University of Nebraska, Lincoln's (UNL’s) Fish Conservation Behavior and Physiology Lab , which serves as a locus for research on water management best practices based on fish physiology—work conducted by up and coming scientists as well as more established researchers. Dr. Jamilynn Poletto spoke to EM about how the lab was built and the work that is happening there.
Building a customized solution
“My problem was that in the lab we get city water from Lincoln, and any water from any city in the country has chlorine and chloramine in it,” explains Dr.Read More
Cary Institute of Ecosystem Studies , an independent environmental research organization in Millbrook, NY, is a leader in environmental monitoring – particularly long-term monitoring that spans decades.
Steve Hamilton is a freshwater ecologist at Cary Institute and professor at Kellogg Biological Station , a member of the Organization of Biological Field Stations ( OBFS ), at Michigan State University. Hamilton explains, “Environmental monitoring is how ecologists keep a finger on the planet’s rapidly-shifting pulse. By tracking ecological indicators over long timescales, we can identify patterns and better understand how ecosystems are changing. This understanding will guide us as we work to adapt to and mitigate environmental degradation.Read More
