The X2-SDL Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in lakes, streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with three sensor ports for connection to industry-standard digital interfaces including RS-485, RS-232 and SDI-12. Additional sensor inputs are available through the use of adapters. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the X2-SDL is truly submersible. The housing and battery compartment are completely sealed and waterproof.
When it comes to field ruggedness, the NexSens X2-SDL is in a class of its own. The housing is constructed of impact-resistant PVC and includes two elastomer bumpers for long-term deployment in close-fitting pipes and buoy ports. Internal circuit boards and communication modules are shock mounted and all access ports incorporate redundant sealing. The X2-SDL withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wireless remote communication, the Wi-Fi, cellular, satellite, and radio antennas are also waterproof.
The X2-SDL can be powered autonomously by sixteen D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. Common sensor connections include multi-parameter sondes, water quality sensors, temperature strings, ADCP's, water level sensors, and weather stations. Optional integrated Wi-Fi, cellular or satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.

Digital Mayfly Data Logger Sensor Stations Monitoring Watersheds
For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed. “ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.

Expanding the Port Everglades: Real-Time Monitoring of Water Quality Conditions from Planned Dredging Operation
The Port Everglades in Broward County, Florida, serves large trade vessels and cruiseliners and incoming and outgoing recreational boaters. However, as cargo ships become larger, the port must expand. A dredging project led by the US Army Corps of Engineers will substantially deepen and widen the port's navigation channel to accommodate larger Panamax cargo ships and modern cruise liners. As a result of this project, a large amount of sediment will be displaced into the water column. This suspended sediment may settle outside of the project area, burying benthic organisms like corals, and possibly carrying harmful particulates to other regions. [caption id="attachment_39497" align="aligncenter" width="2560"] A CB-950 and CB-25 deployed on site at Port Everglades.

It’s Time to React to Water Quality: Proteus Multiparameter Probe aboard NexSens Buoy
Water quality monitoring is essential for safeguarding public health, protecting ecosystems, and ensuring the sustainability of water resources. Contaminants such as industrial pollutants, agricultural runoff, and sewage discharge can severely impact aquatic life and pose serious risks to human health if left unchecked. Traditionally, water quality monitoring has been a slow and labor-intensive process, requiring samples to be collected, transported to a lab, and analyzed—a process that can take days. However, with the advancement of real-time sensor technology, environmental agencies, researchers, and industries can now monitor water quality instantly.
