Why Buy From Fondriest?


The Reverse "Y" Adapter has two male plugs with special power isolation circuitry for added safety. When one plug is connected to a receptacle, the circuitry isolates the second plug. The reverse "Y" provides 50A 125/250V power when only two 30A 125V receptacles are available.
Note: Reverse "Y" will NOT work with 50A, 125V, 3-wire inlets. Power is provided in both circuits to the 4-wire inlet, but the dock side receptacles limit the current in each circuit to 30A. The two 30A 125V receptacles must be supplied from a single power source providing from 208V to 250V between them for proper operation.

Boise River Watershed Watch Shows Volunteers Issues River Faces

Having just wrapped up its ninth year, the Boise River Watershed Watch program is an increasingly popular citizen science program in Boise, Idaho. It takes interested volunteers and joins them with expert scientists from the U.S. Geological Survey (USGS) who teach them about the river’s health and sampling water quality using transparency tubes, dip nets and chemical test kits. “Our focus is to educate folks on the parameters that we measure, to give them an idea of the river’s health,” said Tim Merrick, public information officer at the USGS’ Idaho Water Science Center. “So they can collect data on the river’s conditions and get plugged in.

New Benthic Underwater Microscope Captures Coral Wars

Researchers from Scripps Institution of Oceanography at the University of California - San Diego have designed and built a diver-operated underwater microscope to study millimeter-scale processes as they naturally occur on the seafloor. The research team has observed coral turf wars, coral polyp “kissing” and much more using the new microscopic technology. Many important biological processes in the ocean take place at microscopic scales, but when scientists remove organisms from their native habitats to study them in the lab, much of the information and its context are lost. In a quest to overcome this challenge, Scripps oceanographers developed the new type of underwater microscope to image marine microorganisms in their natural settings without disturbing them.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.
