underwater data logger
The NexSens SDL500 data logger is designed for remote environmental data logging applications with manual data upload via laptop or desktop computer.
The SDL500 is powered via 8 x D-cell batteries or there is an option to install solar panel power pack for long term, remote deployments.
- Five sensor ports for connection to industry-standard digital and analog sensor interfaces
- Powered by (8) D-cell alkaline batteries or optional 5-watt solar power pack
- Withstands extreme wave action, drops, floods, and periodic & long-term deployment underwater
- Compatible with a range of environmental sensors from Edaphic Scientific including dissolved oxygen, dissolved CO2, pH, EC, turbidity and more…
The SDL500 Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with five sensor ports for connection to industry-standard digital and analog interfaces including RS-485, SDI-12, 1-wire temp string, 0-2.5 VDC, pulse count, and more. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the SDL500 is truly submersible. The housing and battery compartment are completely sealed and waterproof.
When it comes to field ruggedness, the NexSens SDL500 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 SDL500 withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wireless remote communication, the radio, cellular, and satellite antennas are also waterproof.
The SDL500 can be powered autonomously by eight D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. The data logger incorporates the same analog and digital interfaces as the popular NexSens iSIC data loggers. Common sensor connections include multi-parameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, rain gauges, and weather stations. User-supplied sensor cable assemblies can also be connectorized and tested at the factory for SDL500 integration. With this sensor interface versatility, the measurement possibilities are endless.
