The Seametrics CT2X is a conductivity and temperature sensor with built-in data logging. Incorporating a 4-pole epoxy and graphite electrode cell, it is extremely durable and resistant to data interferences — making it excellent for use in rugged field conditions.
The CT2X also comes with Seametrics' powerful, easy-to-use Aqua4Plus and Aqua4Plus Lite software, affording the user extensive control, including real-time monitoring, flexible programming, and versatile data display options.
- Measures conductivity, total dissolved solids, and temperature
- Ranges from 10 microsiemens/cm to 100,000 microsiemens/cm
- Pressure and level option available
- In-field calibration utilities
- Narrow 0.75″ diameter, 12.5″ or 16″ length (depending on version)
- Linear and nLFn temperature compensation
- Up to 349,000 records in non-volatile memory
- 316 stainless steel, fluoropolymer, and PTFE construction (titanium optional)
- Digital industry standard RS485 interface
- Available with a variety of cable options—including polyethylene, polyurethane, and FEP Teflon
- Modbus and SDI-12 protocols available
- Easy export to spreadsheets and databases
Questions & Answers
How is the CT2X powered?
The CT2X is powered by two, replaceable lithium 'AA' batteries for up to 12 months (15 minute sample interval) or with a 9-15 VDC external power supply.
How is the conductivity reading compensated for temperature?
The logger uses correction factors to compensate for changes in conductivity readings with temperature. Typically a 2%/degree C change is seen.
How is data obtained from the logger?
Using a USB to RS-485 communication cable, the logger is automatically detected by a PC running AquaPlus 2.0. From the dashboard users can download data and change settings.

Monitoring Buoy Supports Nautical Archaeology
For as long as humans have inhabited Europe’s Atlantic coast, the ocean has been a great source of wonder and mystery. History is full of fascinating tales of epic endeavors, new discoveries of fearless explorers, fishing communities inextricably linked to the bounties of the sea, cultural interactions both peaceful and not, and voyages that went awry during monumental storms or simply due to bad luck. In the south of Spain, at the boundary between the Atlantic Ocean and the Mediterranean Sea, one such tale involves a long-lost merchant ship that went undiscovered from the 16th century until 1984. Believed to be carrying valuable goods from Italy, it sank just across from Gibraltar in the Algeciras Bay at a point called La Ballenera.

Staying Within Budget: Carbon Planning
While we usually concern ourselves with budgeting money or time, we should be thinking about another type of budget: the carbon budget. The carbon budget refers to the amount of carbon exchange, especially carbon dioxide, allotted on an annual basis to prevent the earth from reaching an increase of 2-degrees Celsius all over the globe. If a 2 degree increase does occur, global warming effects are expected to be catastrophic and irreversible. In order to know how close we are to reaching the carbon budget, an extensive knowledge of types of carbon input and their magnitudes, as well as their fluctuations over time, is needed.

IoT for Smarter Aquaculture
With aquaculture booming, IoT may be the future of the market. Fish have been farmed for millennia but only recently has the industry achieved such a vast scale. As overexploitation and climate change threaten wild fish stocks, aquaculture is increasingly framed as an alternative that can provide a low-carbon, healthy protein source. But, as the global population grows, the industry has the monumental task of meeting the increasing demand for seafood. In order to provide higher yields economically and sustainably, it is turning to the Internet of Things, or IoT. IoT refers to technology that pulls data from smart sensors to the Cloud and crunches it using analytic software tools, including artificial intelligence (AI), to monitor and improve efficiency or productivity.
