Why Buy From Fondriest?


The Extech PQ3470 simultaneously displays harmonics and waveforms on a large dot-matrix, sun-readable, numerical, backlit LCD with easy-to-use onscreen menu. This instrument logs up to 30,000 reading on a removable SD memory card in Microsoft Excel® format with a full system analysis with up to 35 parameters including: V(phase-to-phase), V (phase-to-ground), A (phase-to-ground), KW / KVA / KVAR / PF (phase), KW / KVA / KVAR / PF (system), KWH / KVAH / KVARH / PFH (system), and phase angle.

Users can select 200A or 1200A current clamps with flexible current probes. The adjustable current transformer (1 to 600) and potential transformer (1 to 1000) ratio are available for high power distributuion systems.

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.

Parasite Behind Yellowstone River Fish Kill Found In Other Rivers

A parasite that caused a massive fish kill in Montana’s Yellowstone River has been found in at least seven other rivers in the state, according to the Bozeman Daily Chronicle . Scientists with the Montana Fish, Wildlife and Parks department made the find. So far, the parasite has been confirmed in the upper and lower Madison, East Gallatin, Bighorn, Stillwater, and Boulder Rivers. It had already been confirmed in the Jefferson and Shields Rivers. The microscopic parasite causes proliferative kidney disease, one of the most serious diseases to impact whitefish and trout. The effect of the disease on Yellowstone’s fish populations is exacerbated by other stressors like near-record low flows, consistent high temperatures and the disturbance caused by recreational activities.

ESPniagara Tracks Algal Toxins In Lake Erie, Protects Drinking Water

It may have taken 20 years and $20 million to develop, but Lake Erie researchers working to fight harmful algal blooms (HABs) now have a new tool to safeguard drinking water: ESPniagara. The advanced sampler has been called a “lab in a can” for its ability to sample microcystins, the most common algal toxin these days, in almost real time. The big gadget’s name is a mashup between “ESP,” for environmental sample processor, and the name of Admiral Oliver Hazard Perry’s ship during the War of 1812. “We wanted to name it something that was significant to Lake Erie,” said Tim Davis, molecular biologist and lead HABs researcher at the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Lab (NOAA GLERL) in Ann Arbor, Mich.
