The Extech Precision Hygro-Thermometer has a high 2% relative humidity accuracy with grains per pound and grams per kilogram. The meter has a less than 30 second response time and its slim design with rubberized sides make for a better grip for one handed operation. The dual backlit screen simultaneously displays humidity or GPP (g/kg) plus temperature, humidity or GPP (g/kg) plus dew point, or humidity or GPP (g/kg) plus wet bulb. Additional meter features include data hold, min/max function, automatic power off with disable, and low battery indicator.

Utah’s Canyonlands Research Center: A Great Study Location for Climate Effects on Ecosystem Processes, Community Dynamics and More
Canyonlands Research Center (CRC) is situated at The Nature Conservancy’s Dugout Ranch , over 5,200 private acres of research study area. One of CRC’s primary roles is to facilitate research and monitoring work of university and federal researchers. CRC is located adjacent to Canyonlands National Park , which extends over more than 337,000 acres of public land. CRC also partners with many organizations, including the Bureau of Land Management, USFS, NPS, USGS, Utah State University, and the Utah Division of Wildlife Resources to identify the most pressing research needs in this region.Read More
Recent research from a University of Guelph (U of G) team reveals that warmer temperatures caused by climate change are forcing species to alter their behavior, causing food webs in Ontario lakes to transform. As temperatures warm, larger species hunt new prey in deeper waters, changing the ways nutrients and energy flow in lakes and triggering a “rewiring” of food webs.
Dr. Timothy Bartley , study lead author and a post-doctoral researcher in the U of G's Department of Integrative Biology , spoke to EM about the work .
“I got started on this when I first began graduate school and joined an ongoing project, which was a collaboration with the Ontario Ministry of Natural Resources and Forestry ,” explains Dr. Bartley.Read More
Some of the most interesting data in the world of river and stream monitoring come at times when it's practically impossible to capture—during extreme weather events, for example. Timing alone makes capturing unusual events a challenge, and these kinds of issues have prompted researchers to use classic monitoring data along with new technologies to develop and improve hydraulic modeling for estimating river flows.
Steven Lyon , a Conservation Scientist with The Nature Conservancy, Professor at Stockholm University and Associate Professor at The Ohio State University, spoke with EM about the research .Read More
