|TM500||12-channel datalogging thermometer with 6 thermocouple types|
|Usually ships in 1-2 weeks|
The Extech TM500 12-Channel Thermoucouple Datalogger allows for a wide range of applications with 6 thermocouple types: J, K, E, T, R, and S. It displays channel 1 to channel 8 or channel 9 to channel 12 on the screen and data can be recorded from all 12 channels simultaneously onto an SD card in Excel format for further analysis. In addition, an RS-232 port allows data streaming to a PC. User programmable sampling rates can be set from 1 to 3600 seconds.

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
In early 2020, Michigan found itself facing one of the worst outbreaks of Covid-19 in the country. Though it’s close to second nature now, businesses, schools and governments were suddenly forced to conduct business without close contact. Universities and research institutions had to pause some scientific research. Whatever was able to continue slowed to a crawl.
Around the Great Lakes, a network of buoys monitors dozens of water quality parameters and lake conditions, reporting them in real time. This year, the monitoring season was cut a bit short as Covid-19 restrictions hit in the weeks before buoys were set to be deployed.Read More
