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

Long-Term Monitoring in the Chautauqua Lake Watershed
With a widely developed shoreline, Chautauqua Lake experiences influxes of non-point source pollution that have historically impacted the health of the lake. The Chautauqua Lake Association (CLA) has been monitoring the lake for over two decades, reporting on changes that have occurred over the years. A pair of local lake advocates, Jane and Doug Conroe, have lived on the lake for over 40 years and have played an important role in establishing monitoring programs and facilitating consistent data collection throughout the watershed. Doug has been involved with the Chautauqua Lake Association (CLA) since the pair moved to the area in 1980, and is currently serving as the Executive Director.

No Red Herrings: Data Driving the Largest Salt Marsh Restoration in the NE USA
The Herring River system encompasses around 1,000 acres in the Towns of Wellfleet and Truro, Massachusetts. In 1909, the Chequessett Neck Road dike was built at the river’s mouth, drastically limiting tidal flow. Today, it’s one of the most restricted estuaries in the northeastern United States. As a result, the area has suffered environmental decline, including poor water quality, hypoxia, lower pH, and salt marsh degradation. In 2023, the Town of Wellfleet received $14.7 million from NOAA’s Office of Habitat Conservation to fund the Herring River Restoration Project (HRRP). Francesco Peri, President and CEO at Charybdis Group LLC, uses a network of NexSens data loggers to monitor water level and water quality on the Herring River.

Carbon and Nutrient Monitoring in the Great Lakes Using Satellite Observations
Carbon and nutrients are the foundation of lake food webs and play an important role in the chemical and physical processes that shape aquatic ecosystems and various lake dynamics. Studying these cornerstones can help improve understanding of other lake conditions like harmful algal blooms, hypoxia, and phytoplankton community composition. The way in which these characteristics are monitored varies, though many rely on a proxy approach wherein parameters are extrapolated from the measurement of a different parameter. An assistant professor at Cleveland State University, Brice Grunert, is working to improve current strategies and take a satellite approach to monitoring the Great Lakes.
