Overview
The Seametrics PT2X is ideal for observing flow patterns, testing pumps, and monitoring groundwater, well, tank and tidal levels. A pressure and temperature sensor with integrated data logging, this sensor is constructed with 316 stainless steel, fluoropolymer, PTFE—providing highly accurate readings in rugged and corrosive field conditions.
Sensor
- Measures pressure, temperature, and time
- Available in absolute, gauge, or sealed gauge
- Thermally compensated
- ± 0.05% FSO typical accuracy
- Low power: 2 internal AA batteries
- External power options (12 VDC) with AA’s acting as backup
- 316 stainless steel, fluoropolymer, and PTFE construction (titanium optional)
- Available for both Modbus and SDI-12 protocols
Data Logger
- Non-volatile memory: Data will not be lost in the event of a power failure
- Flexible, multi-phase logging sequences: Measure at specified intervals and save instructions to disk for reuse
- Pause logging feature: Temporarily pause the logging while repositioning or transporting the sensor
- Delayed start feature: State a specific future start time, making it easy to set several sensors to start at the same time
Cabling & Networking
- Wireless connectivity
- RS485 network: Allows several sensors to be networked together and provides much longer cable leads
- Field-serviceable connectors: Easily remove the connector, route the cable through well seals, walls, or conduit, and then replace the connector
- Available cableless or with a variety of cable options, including polyethylene, polyurethane, and FEP
Software
- Comes with free Aqua4Plus control software to get up and running immediately
- View data in real-time
- Easy export to spreadsheets and databases
- Barometric compensation utility for use with absolute sensors
- Update sensor via firmware while in the field

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.

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.
Read MoreSoundscapes 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.
