The SDL500 Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in or near water without fear of accidental flooding.
- QUICK SPECS
RuggedThe SDL500 is designed with impact-resistant PVC, two elastomer bumpers, shock-mounted electronics and redundant seals. It can withstand extreme wave action, floods and underwater deployment to 200 ft.
Extended Battery LifeThe SDL500 operates for months on eight D-cell alkaline batteries. For longer deployments, sixteen D-cell alkaline battery packs and solar charging options are available.
Sensor ConnectionsThe SDL500 is configured with five sensor ports to interface with water quality sondes, water level sensors, soil sensors, and more. Supported sensor interfaces include RS-232, RS-485, SD-12, VDC, and mA.
Communication OptionsReal-time telemetry options include cellular, radio, and satellite. All communication modules are securely housed within the submersible enclosure, and a waterproof antenna attaches to the top connector.
Buoy IntegrationThe CB-50 data buoy is designed to accommodate the NexSens SDL500 submersible data logging system for unattended deployment in lakes, rivers, and coastal waters.
