This kit provides power measurement and analysis plus datalogging of single and 3-phase/3-wire or 3-phase/4-wire systems. Model PQ3350-1 offers 1200A 12" flexible current clamp probes while model PQ3350-3 offers 3000A 24" flexible current clamp probes that can be used to wrap around bus bars or wire bundles. The large LCD simultaneously displays up to 35 parameters for harmonics and waveform. An optically isolated USB interfaces with the software to download waveforms, power parameters, and harmonics.

REASON Project Puts Water Quality Instrumentation in Dams

Where and how to monitor water quality is always a challenge, particularly in complex aquatic ecosystems. The new REASON Project from a team at Clarkson University is working to demonstrate the utility of using water quality instrumentation in dams on major rivers in the Great Lakes system. Clarkson University Professor of Biology Michael Twiss spoke with EM about the new approach their team is taking at the Moses-Saunders Power Dam across the St. Lawrence River and the benefits the development of smart infrastructure such as this might offer. “The upper St. Lawrence River is defined as that which leaves Lake Ontario and is just upstream from the city of Montreal,” explains Dr. Twiss.

A Lesson in Persistence: Taking On Cyanobacteria in Florida

As we hear more and more about algal blooms of different kinds across the United States, teams of scientists are working hard to ensure that they don't become our new normal. One project in Florida is taking a multi-disciplinary approach to the problem—including genetic analysis. The team's work is part of a full-court press in Florida recently, making a serious push to understand what is triggering more frequent blooms. Jose Lopez, Ph.D. , of Nova Southeastern University , the primary investigator on the genetic analysis portion of the project, spoke to EM about the project and his work on it. “This is a very good project,” explains Dr. Lopez. “We're excited about it, and it's a lesson in persistence.” Dr.

Keeping TABS on the Texas Gulf Coast

From extreme weather such as Hurricane Harvey to spills and other accidents, the Gulf Coast of Texas is no stranger to dangerous situations. This is where the data provided by the Texas Automated Buoy System ( TABS ) comes into the picture. Among the nation's most successful and longest-running coastal ocean-observing systems at the state level, the TABS real-time oceanographic buoy system monitors currents, waves, salinity, winds, and other parameters. Dr. Anthony Knap , director of Geochemical Environmental Research Group (GERG) and a Professor of Oceanography at Texas A&M University, spoke to EM about working with TABS. “TABS has been running now for 24 years,” explains Dr. Knap.
