Overview
The Extech Heavy Duty Dissolved Oxygen Meter features a large 1.4" LCD that displays both oxygen and temperature values. The meter measures dissolved oxygen from 0 to 20.0mg/L and 0 to 100.0% oxygen and temperature from 32 to 122°F (0 to 50°C). The automatic temperature compensation function ranges from 0 to 50°C via the temperature probe sensor built into polarographic type oxygen probe. The meter has a fast 0.8 second sampling time and recalls min/max/avg readings.

PC Interface
The built-in RS-232 PC serial interface gives users the option to connect to a PC using the optional data acquisition software and datalogger. The software and serial cable enable users to display and capture readings on a PC and set time intervals and alarms.

Questions & Answers
How do I calibrate my meter?
To calibrate, ensure that the sensor is disconnected from the meter. Turn the meter on and slide the O2/DO selector to the O2 position. Press the zero key to null the meter and connect the DO sensor to the top of the meter. Allow the meter to stand for at least five minutes until the display stabilizes. Press the O2 cal key and the display will indicate approx 20.9 (typical O2 in air)
Does the meter have an auto power off feature?
Yes, the meter includes an Auto Shut off feature that preserves battery life. The meter will automatically turn off after 10 minutes of inactivity.

Climate Change and Microplastics: Monitoring Lake Champlain

Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems.  As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work.  Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.

Current Monitoring after the Francis Scott Key Bridge Collapse

On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.

Soundscapes of the Solar Eclipse: Citizen Science Supporting National Research

On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth.  The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.
