The Extech Humidity & Temperature Chart Recorder features simultaneous numerical and graphical display of humidity and temperature readings, plus time and date. The recorder measures humidity from 10% to 95% relative humidity, and temperatuer from -20.0°F to 140.0°F. The included LabView-based software calculates and graphs dew point, wet bulb, and grains per pound. The large dual graphical LCD displays readings with adjustable vertifcal and horizontal TAC resolution.

 

The internal memory records up to 49,000 data points that can be transfered to a PC via the RS-232 serial port for further data analysis. The detacheable probe extends up to 1 meter for measurements in closed environments. An audible and visual alarm will sound if high/low setpoints are exceeded. The output socket is used for an optional external alarm module.

 

Applications include monitoring and recording laboratory or clean room temperature and humidity history, recording process conditions, generating warning when conditions are outside required limits, monitoring controlled environment areas such as freezers, storage areas, and other critial areas, and storing humidity and temperature historical data for report generation.

Monitoring Water Pollution in Keweenaw Bay

As much as climate change and pollution impact current generations and present environmental conditions, the compounding damages will continue to wreak havoc against generations to come if no actions are taken. This idea is central for scientists who focus their research on monitoring, analyzing and responding to environmental data. Researchers like Dylan Friisvall, the water quality technician for the Keweenaw Bay Indian Community (KBIC) Natural Resources Department (NRD) , have dedicated their careers to monitoring pollution and water quality in order to protect resources for the future. “One of the best parts of my job is just being outdoors, it makes my day go by faster because I get to enjoy the fresh air, and help do my part in protecting the environment,” says Friisvall.

Balancing Forest Biodiversity and Land Use Benefits

A new study by Fangyuan Hua, Assistant Professor at Peking University’s Institute of Ecology, compiles data showing that restoring native forests results in better biodiversity, greater carbon storage and more soil conservation and water provisioning benefits. However, the data also indicates that tree plantations are better at providing wood. The benefits and downsides of each forest type lead to tradeoffs in land management practices. In their paper , Hua and colleagues explore the advantages and disadvantages of different forest types, hoping to point the way toward better forest restoration practices. They hope to encourage practices that balance environmental goals with wood production needs.

Protecting Endangered Species: Conducting Mussel Surveys

*This is part two of a two-part story on endangered mussels. To read part one, click here * With over 300 endangered mussel species in the United States, environmental agencies like EnviroScience rise to the challenge of protecting these vital species. When new construction sites are determined, the Endangered Species Act steps in to protect any endangered wildlife within the impacted area. Unfortunately, the protocols surrounding these protections can be complex and difficult to understand, making the work of scientists like Greg Zimmerman, Corporate Vice President for EnviroScience and an endangered mussel surveyor, vital to protecting biodiversity.
