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|

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.

Closer to the Midwest, we look at surface mining impacts on Appalachian streams , plastics in the Great Lakes , and wildlife returning to Michigan’s Rouge River .Read More
The Charles River used to be a swimming hotspot for Cambridge and Boston residents.
Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river.
An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.Read More
The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use.
Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.Read More
