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.

For decades, commercial fishing for yellow perch was allowed in southern Lake Michigan. This persisted until 1996 when it was outlawed, giving perch stocks there some time to recover. Scientists had for some time assumed that this fishing ban would not affect the reproduction cycles of the perch quickly and that they were going to need a long time to revert back to the cycles they relied on before commercial fishing ever started. But new research led by scientists at Purdue University finds that maturation schedules of yellow perch in southern Lake Michigan are much more resilient than had been previously thought possible.Read More
Largely seen as pristine and relatively untouched by human activity thanks to its protected status, the portion of the Colorado River flowing through Grand Canyon National Park is anything but, according to recently published research. This is evidenced by high levels of selenium and mercury found in the fishes there. Scientists from many institutions were involved in the years-long work, full results of which have been published in the journal Environmental Toxicology and Chemistry. It was led by the U.S. Geological Survey, but perhaps the contributors from Idaho State University got the best end of the stick. They were looking into the food webs of the river to evaluate concentrations of selenium and mercury gathering in fish.Read More
For all the straightforward groundwater monitoring applications that the folks at Heron Instruments help with, there are a few that are far from typical. These include projects that take place near remediation sites or not far from waste disposal operations. Realizing that customers working in those sorts of projects are in need of a more robust option, the company has released the dipper-Tough . The new water level meter takes inspiration from Heron’s popular dipper-T , while throwing in a host of improvements that environmental pros working in groundwater can really appreciate.Read More
