Overview
The Global Water GL500-2-1 Data Logger features two analog channels and one pulse channel for recording data. 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 GL500-2-1 includes Global Logger II Windows software, which allows for easy setup, calibration, upload, and transfer to a spreadsheet program. 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
- Exception
Calibration
The Global Water 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.
Note: 64-bit operating systems are not currently supported.

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania
Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. 
 
In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. 
 
One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” 
 
Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.

Thousands of people flock to the Great Lakes every year to enjoy the freshwater beaches along the coast. As an urban hub with over 2.5 million residents, beachfronts in Chicago have regular visitors as well as tourists that recreate in the bordering Lake Michigan. 
 
According to the Chicago Park District, it is estimated that more than 100,000 residents and visitors per day use Chicago’s Lakefront trail during summer weekends. 
 
Proximity to the Lake is not only a recreational activity for Chicagoans, but also a part of the city’s history due to its role in domestic and international shipping routes. In addition, the Lake serves as a drinking water source and as an essential climate regulator in the region that acts as a natural air conditioning affect.
