The Extech EasyView Light Meter with Memory stores and recalls up to 50 light measurements with relative or real time clock stamp.
The Extech EasyView Light Meter with Memory features a wide measurement range to 99,990Fc (999,900lux) with resolution of 0.001Fc and 0.01lux for taking measurements in direct sunlight. The ripple function excludes the effect of stray light from the primary light source measurement. The measurements are also cosine and color corrected. It stores and recalls up to 50 measurements with relative or real time clock stamp.

Over the past few years, people in Hawaiian waters have been spotting whale sharks more and more often—and researchers are wondering why. Now, the dedicated team of researchers from the Hawaii Uncharted Research Collective (HURC) is working to find out with the Whale Shark Initiative . Chief Technical Scientist Travis Marcoux and Chief Research Scientist Stacia Goecke of HURC spoke with EM about the inspiration for the whale shark research program and its connection to HURC.
“Our Director, Maria Harvey, and Stacia worked on the water in Kona together for many years, and occasionally tour boat operators would report sightings of whale sharks,” explains Dr. Marcoux.Read More
A recent report from the Environmental Defense Fund (EDF) reveals that there is lead present in drinking water among childcare centers in different parts of the country. The report clarifies where problems are appearing, and sets forth new, more stringent recommendations for standards.

Lead is unsafe in drinking water, at any level. It is especially risky for children because lead exposure can impair normal brain development, leading to problems learning and behavioral issues.
Despite understanding the risks that lead poses to children, there remains what the EDF report calls “a toxic legacy of lead” in the US.Read More
University of California, Santa Barbara (UCSB) stream ecologist David Herbst , a research scientist with Sierra Nevada Aquatic Research Laboratory (SNARL) , is committed to exploring the little worlds inside stream riffles and pools, one overturned stone at a time. Living in these small, dynamic systems are the benthic invertebrates that offer up clear signals about water quality and stream health.
Recent research from Dr. Herbst and his team, published in the journal Hydrobiologia , elucidates the connections between the communities of benthic invertebrates that live in stream riffles and pools, how and why they move as conditions change, and what changing conditions mean for the stream and the rest of the local ecosystem.Read More
