Global Water GL500-2-1 Data Logger
- Rugged and easy to use
- Records over 81,000 readings
- Accepts any 4-20 mA signal
|FR0000||GL500U-2-1 data logger, USB|
|Usually ships in 1-2 weeks|
The GL500-2-1 Data Logger features two analog channels and one pulse channel for recording data. The data logger records over 81,000 readings and has four unique recording options: fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception. Start and stop alarm times can be programmed to synchronize multiple loggers, delay sampling until a preset time, or limit the number of recordings during a day. The GL500U-2-1 USB model is great for direct connection to a laptop or desktop PC.
The GL500-2-1 can monitor two 4-20mA sensors and features a scalable digital input that accepts switch closure signals and pulses from various external devices. The logger provides switched power to the sensors based on the programmable sample interval and sensor warm up time settings. Two- and three-wire sensors can be quickly connected to the datalogger’s internal terminal strip and calibrated via the included Global Logger II software.
The GL500-2-1 includes Global Logger II Windows software, which allow for easy setup, calibration, upload, and transfer to a spreadsheet program. NOTE: 64 bit operating systems are not currently supported.

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
