Details

The Extech 2-Channel Digital Oscilloscope's dual channel optimizes the position, range, timebase, and triggering to guarantee a stable display of virtually any waveform. The multimeter automatically measures twenty different functions including frequency, cycle, average, peak to peak, and RMS. Up to 4 waveforms can be stored and recalled at one time.

Multiple modes ensure the most accurate data possible: average mode for smoothing waveforms, and persistence mode for observing dynamic signals. Autoscale automatically configures trigger mode where the oscilloscope can measure a waveform without a triggering condition. XY mode and FFT function help the viewer understand the relationship between channels one and two.

Other features include 20MHz bandwidth, waveform math, and a real time clock. The included USB interface and compatible software enable the user to transfer waveforms and data to any PC.

Narragansett Nature: Remote NERR is a leader in salt marsh stressor studies, crab studies and contributions to Rhode Island environmental policies

Unique among the 29 National Estuarine Research Reserves (NERRS), Narragansett Bay National Estuarine Research Reserve (NBNERR ) is made up of four islands: Prudence, Patience, Hope and Dyer. Protecting about 4,400 acres of land and water, NBNERR is a great place to see a variety of coastal habitats. There are upland maritime forests, coastal pine barrens, sandy beaches, cobble shorelines, salt marshes and open grasslands. NBNERR also has excellent hiking, fishing, clamming and bird watching. “If you want to see us, though, you’ll need to hop on a ferry,” says Bob Stankelis , NBNERR Reserve Manager. “Or you’ll have to take a boat. We’re not that easy to get to. But to be honest, that’s one of the big things residents here like about it: its remoteness.

Acid Rain Data Helping Scientists Tackle Water Quality Issues

Since the 1980s, scientists from the Vermont Department of Environmental Conservation (VT DEC) have been sampling water from acid-impaired ponds and lakes and tracking data related to acidity. The line of inquiry began in response to concerns about acid rain, but DEC scientists now find that the long-term monitoring is not only proving the efficacy of the Clean Air Act but also improving local water quality. Guarding the environment in Vermont Rebecca Harvey is a VT DEC scientist, and monitoring the state's waterways for acidity and other problems falls in part to her. Dr. Harvey corresponded with EM about this work.

Advanced Oxidation Processes for Wastewater Treatment

In the ongoing quest for better wastewater treatment, a team of researchers from the University of California, Riverside (UCR) have developed a technique to improve the way Advanced Oxidation Processes (AOPs) remove pollutants from wastewater dramatically. AOPs remove organic materials from water using oxidation. These AOP reactions take place when hydrogen peroxide, a powerful oxidizing agent, decomposes, leaving hydroxyl radicals along with oxygen and water behind. This makes the processes appealing, but until now they've required both a long period of time and large amounts of both hydrogen peroxide and ferrous salt (Fe2+, a divalent iron ion). The Fe2+ acts like a catalyst, but also produces a secondary pollutant in the form of an iron-containing sludge.
