Extech LT300 Light Meter
The Extech Light Meter measures light intensity up to 20,000 Foot-candles or 200,000 Lux.
- Data hold freezes reading in the display
- Peak mode captures highest reading
- Relative mode indicates change in light levels
|Usually ships in 1-2 weeks|
|LT300-NIST||Light Meter, NIST traceable|
|Usually ships in 1-2 weeks|
The Extech Light Meter measures light intensity and changes in light levels via the relative mode. The peak mode captures the highest readings, and data hold freezes the reading on the display. The remote light sensor is attached to a 12 inch coiled cable which can be expanded to 24 inches. The meter utilizes precision photo diode and color correction filter, and includes cosine and color correct measurements. The min/max function stores maximum and minimum readings. The light meter is ideal for measuring parking lot illumination, security lighting, and night ATM areas.

The North Carolina Wildlife Resources Commission ’s Inland Fisheries Division has been working to restore brook trout in the state. Coldwater research coordinator Jacob Rash, who works with the brook trout team technicians on this project, spoke to EM about the work.
“In North Carolina, brook trout are our only native trout species,” explains Mr. Rash. “With that come biological and ecological considerations as well as cultural importance. A lot of folks here grew up fishing for brook trout with their relatives, so it's an important species that we work to try to conserve. We've done quite a bit of work to figure out where those brook trout populations are and what they are, in terms of genetics.Read More
Each year in Germany, as many as 450,000 living fish undergo live animal experiments to test how fish-friendly hydroelectric power plants in the country are. The idea is to discover how readily the fish can move through hydroelectric turbine installations in order to ultimately reduce mortality rates.
Of course, subjecting live fish to a potentially deadly test to save others is a bitter irony. And it's one that a team of scientists from the RETERO research project hopes to eventually mitigate with a robotic fish for testing.
EM corresponded with Olivier Cleynen and Stefan Hoerner from the University of Magdeburg about the complex flow conditions that set the parameters for the project.Read More
News stories about dogs getting sick from harmful algal blooms (HABs) in lakes have caused worry among members of the public this summer more than once. But Regional Science Consortium (RSC) Executive Director Dr. Jeanette Schnars and a dedicated team are bringing awareness about HABs to the public with the Mobile HAB Lab.
“We just launched the HAB Citizen Scientists program this year,” explains Dr. Schnars. “It helps us work with people, especially people who spend time at marinas frequently, that are out there all season long.”
The season for boaters at Presque Isle, where RSC is located, starts in mid-May and usually continues through the beginning or middle of October.Read More
