Why Buy From Fondriest?


The Extech 160W power supply offers high efficiency electrical power conversion for greater energy conservation and lighter power. It constantly calculates and adjusts the voltage and current limit points according to the available maximum power (160W). At maximum current, 10A, the voltage is limited to 16V, and at maximum voltage, 42V, the current is limited to 3.8A. A dual action rotary encoder control with push knob provides smooth, accurate and quick setting of voltage/current.


Three on-board user-defined voltage and current presets offer quick recall of frequently used test settings. The remote control feature permits output On/Off and voltage/current adjustments without the need to touch the front panel of the power supply. Setting, changing, and verifying the current limit level is convenient and can be performed without output pole spiking. A USB port offers PC connectivity for programming and running ramp/soak cycles with 20 programmable sets of voltage/current and varying test durations, up to 999 cycles. The DC ramp and waveform generator can either be panel set or set by the supplied software which previews the final waveform.


Applications and industries where the DCP42 can be employed include laboratory, telecommunications, production testing, field testing, and DC network powering.

Volunteer Water Quality Monitoring Networks at the Heart of Citizen Science Movement

Lately, citizen science initiatives have been getting noticed by laypeople and mainstream media outlets. As everyday people become aware of ways they can get involved in actual scientific research, more of them are doing so—especially teachers and parents working with children. But this citizen science wave isn't actually a new thing. It has been growing outward from its core in volunteer water quality monitoring networks for years. Around the country, volunteers have been quietly monitoring the water quality in lakes, streams, rivers, marshes, and other surface waterways for decades. These highly successful programs have been supporting better water quality in communities across America, and in doing so have also formed the heart of the modern citizen science movement.

US Steel Dumping Chromium: Citizens Fighting for Lake Michigan, and Drinkable Water

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.

Monitoring the Mississippi: Wild Celery, Redhorse and More

The Upper Mississippi stretches from headwaters at Lake Itasca, Minnesota, all the way to Cairo, Illinois, about 1,250 miles. It includes picturesque wilderness areas complete with waterfalls, limestone bluffs and expansive valleys. It has attracted many campers, hikers, fishing enthusiasts and people seeking to launch their favorite boats or canoes. It has also been a haven for environmental researchers. Since 2016, Jeff Houser is the Science Director for the Long Term Resource Monitoring element (LTRM) of the Upper Mississippi River Restoration Program (UMRR).  Previously, he led the LTRM water quality component from 2003 until 2016.
