Rugged stainless-steel float bodies for lakes, reservoirs, harbours and rivers. Two form factors.
Stainless steel, protective coating. Central mast mount for antenna, logger and weather shelter. Stainless-steel pass-through for sensor chains and mooring.
Use cases: early-warning systems (e.g. dissolved oxygen), temporary monitoring campaigns, vertical thermal stratification.
Specifically designed for shallow waters, operational from 20 cm depth. Compact, stable, long-term durable. Customisable with various sensors.
Use cases: lakes, ponds, wetlands, slow-flowing river segments.
