Why Buy From Fondriest?


The Extech EasyView Hygro-Thermometer measures relative humidity, temperature, dew point, and wet bulb. The compact and rugged design features a large display and bargraph for visual analysis of data points. The screen displays two parameters simultaneously set with user preference. The min/max function stores and recalls highest and lowest readings. The data hold function freezes readings on display. The remote capacitance sensor extends to 39 inches (1m) through the coiled cable. 


Model EA25 has all of the capabilities of Model EA20 but also datalogs up to 15,000 records plus automatic time function. The timer function displays the elapsed time in minutes, seconds, days, or hours, to the minimum and maximum readings. This model also has a built-in RS-232 PC serial interface to connect to a PC and view data with the Windows compatible software. Applications include monitoring relative humidity and temperature in factories, clean rooms, and greenhouses, and produce reports for overnight or long term humidity and temperature fluctuations.

BRUVS Capturing Deep-Reef Fish Communities

Until recently, it's been difficult for scientists to monitor, inventory, and study deep water fishes. Yet these species are critical to understanding threats posed by climate change, fishing pressure, and pollution, among other factors impacting marine life. Now, teams are using newer technologies to access and document fish abundance and diversity among deeper reef settings. Tiffany Sih , a PhD candidate from James Cook University, has used Baited Remote Underwater Video Stations (BRUVS) with lights to sample deeper habitats (54–260 m), in the Great Barrier Reef (GBR), Australia. Sih corresponded with EM about her recent work , the first study of its kind looking deeper than 100m, and what inspired her to take the deeper dive.

As Arctic Permafrost Thaws, Northernmost Lakes Brown

More than 250 million years ago, massive volcanic activity in the region of what is now Siberia caused “The Great Dying,†a colorful name for the Permian mass extinction that wiped out most of the life on Earth at the time. Once the volcanic activity finally calmed down after a respectable one million years, about 96 percent of life in the ocean and 80 percent of life on land was gone. About 500 gigatons of carbon were left behind in that region, and as the Earth cooled, that carbon was sealed in the Permafrost that covers much of Siberia today. Permafrost is simply ground that stays frozen at or below 0° Celsius (32° Fahrenheit) all of the time. It does not necessarily contain ice; as long as it remains frozen solid, even completely dry ground is permafrost.

Volunteer Water Quality Monitoring Networks at the Heart of Citizen Science Movement

Lately, citizen science initiatives have been getting noticed by laypeople and mainstream media outlets. As everyday people become aware of ways they can get involved in actual scientific research, more of them are doing so—especially teachers and parents working with children. But this citizen science wave isn't actually a new thing. It has been growing outward from its core in volunteer water quality monitoring networks for years. Around the country, volunteers have been quietly monitoring the water quality in lakes, streams, rivers, marshes, and other surface waterways for decades. These highly successful programs have been supporting better water quality in communities across America, and in doing so have also formed the heart of the modern citizen science movement.
