The Extech Heavy Duty Light Meter enhances accuracy by selecting one of four lighting types: tungsten/daylight, fluorescent, sodium, or mercury. The meter utilizes precision diode and color correction filter, and adjusts for cosine and color corrected measurements. The microprocessor assures maximum accuracy through and Fc range of 200.0, 2000, and 5000Fc and a lux range of 2000, 20,000, and 50,000lux. 

 

The built-in RS232 serial interface provides a connection with the optional Windows Data Acquisistion Software that enables users to display and capture readings on a PC, and set time intervals and alarms. The battery operated datalogger module stores over 8000 readings for later transfer to a PC.

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.

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.
