Monitoring Made Simple
ProSwap Logger features a universal port for a wide variety of real-time monitoring applications. Combine any digital smart sensor with the built-in temperature and depth sensors for more comprehensive measurements in a slim profiling package. Build a dedicated system for conductivity, dissolved oxygen, pH, turbidity, or algae monitoring applications with unique customization options.
Continuous Unattended Logging
Ideal for short- and long-term deployments, the on-board memory is capable of holding over 100,000 data sets. With ProSwap Logger, you can view trends in water quality over extended periods of time for a true representation of the ecosystem.
Flexible Deployment
ProSwap Logger is a powerful instrument in a small package. Suspend in groundwater wells, deployment pipes, and other tight or shallow spaces. A variety of power and deployment options are available to fit the needs of your system.
Reliable Connection
An integral cable allows for easy topside communication and data download without removing the sonde from its deployment location. A twist-lock connector provides quick and reliable communication via a dedicated handheld or Kor Software. With convenient options for calibration, deployment setup, and data collection, ProSwap Logger makes it easier than ever to effectively expand you smart watershed.
Digital Smart Sensors
ProSwap Logger is compatible with any individual ProDSS Digital Smart Sensor for fast, easy setup and high quality data. Each sensor features a welded titanium body, auto-recognition, and local storage of calibration for quick swapping. Trusted by water quality professionals, these sensors provide accurate data with advanced technology and proven performance!

In The News
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.
Read MoreStaying 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.
Read MoreIoT 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.
