Ocean Monitoring Instruments
Monitor marine environments with ocean sampling & analysis
OceanPack™ RACK
The OceanPack™ RACK is an autonomous marine monitoring system with a classic FerryBox design in a 19″ rack format. It can be installed in a wide variety of vessels, including research USV and environmental monitoring platforms.
Almost any oceanographic sensor can be integrated into the system, including pCO2, SST, SSS and algae sensors, as well as other devices such as nutrient analyzers, water samplers, weather stations and GPS receivers.
Up to 30 serial devices can be connected simultaneously, and this can be expanded via an optional RS485 bus. Data is recorded on SD cards and can be retrieved via USB.
