Extech RH300 Digital Psychrometer
Description
The Extech Digital Psychrometer calculates T1-T2 differential (air temperature minus external probe temperature).
Features
- Wet bulb measurements without slinging
- Switchable °F/°C temperature units with 0.1° resolution
- Data hold freezes current reading on display
Details
The Extech Digital Psychrometer simultaneously displays % relative humidity, temperature, dew point, or wet bulb or probe temperature. The wet bulb measurements are made without slinging. The meter calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe and T2-dew point. The unique sensor cap design twists to the closed position for protection during storage. Additional meter features include switchable °F/°C temperature, data hold, max/min readings, and automatic power off.

Water Quality Program Changing Lives One Student at a Time
Millions of Americans rely on well water at home, and in Virginia well water supplies about 20 percent of households. The Virginia Household Water Quality Program , run by Program Coordinator Erin Ling at Virginia Tech , is offering well testing across the state, helping the people who use that well water understand how to keep it safe and healthy. EM spoke to Ling and Carroll County High School STEM-Ag Lab Manager Rachelle Rasco about the program. “Our audience was traditionally mostly adults and homeowners, so the ability to reach families that are busy with young children more effectively is always in the back of my mind,” explains Ling.

From Scrub-Jay DNA to Cycles of Carbon, Water and Fire: Archbold Biological Station Offers A Deep Look at Conservation
The oil industry is sometimes viewed as an enemy of conservation. But it was the oil industry that enabled the founding of Archbold Biological Station , one of the members of the Organization of Biological Field Stations (OBFS) . Descended from John Dustin Archbold, President of Standard Oil of New Jersey, Richard Archbold used his private wealth to further the cause of field research and education. He became an explorer, aviator and perhaps most importantly, a research associate with the American Museum of Natural History. He established Archbold Biological Station in 1941 after the father of his friend Donald Roebling (from a famous family himself), donated 1,058 acres of pristine land in the heart of Florida to further Archbold’s research dreams.

Central Lake Superior: Arctic Testbed and Autonomous Proving Ground
This summer, Michigan Technical University unveiled a new Marine Autonomy Research Site , located at the waterfront Great Lakes Research Center . The site is part of an ongoing push to advance autonomy in the marine industry and to help take humans out of the equation when research on the water is dull, dirty and/or dangerous. Dr. Guy Meadows , director of the Great Lakes Research Center (GLRC), spoke to EM about the site. “The project is an initiative of the eight Great Lakes Governors and two premiers of Canada,” explains Dr. Meadows. “The goal is to try and leverage autonomy in the land sector into both the aviation and the marine sector, and we are trying to play a role in that marine sector.
