01
Modular & Scalable
Mix-and-match sensor payloads and platforms — from a single coastal probe to a basin-wide mesh of buoys, masts and seabed frames.
Single node → 200+ node networks
Integrated Ocean Observation Systems
Sensors, platforms, telemetry and software working together to deliver reliable marine data — from the seafloor to the cloud.
Four Measurement-First Product Lines
Pick the line that matches what you need to monitor — water quality, weather, oceanography or the platforms that host them.
Water Quality
Underwater probes for dissolved oxygen, pH, salinity, turbidity, chlorophyll and nutrients — the AquaSense and AquaGo lines.
DO pH Salinity Turbidity Chlorophyll
Explore Water Quality 
Meteorological
Weather masts and buoy-mounted stations measuring wind, pressure, humidity and rainfall — the AeroSense line.
Wind Pressure Humidity Rainfall
Explore Meteorological 
Oceanographic
Wave, current, tide and CTD measurements for ocean dynamics — the OceanSense and WaveSense lines.
Wave CTD Current Water Level
Explore Oceanographic 
Platforms
Smart buoys, shore stations, seabed frames and portable systems that host marine sensor payloads — the OceanBuoy line.
Buoy Shore Portable Custom
Explore Platforms Solutions for every application
Aquaculture operators, offshore developers, research institutes and marine conservation programs — six application areas where Zenocean systems are deployed today.

Engineered for the Ocean
Five things every project team — from coastal pilot to multi-year ocean observatory — tells us they need from a marine instrumentation partner. We build for all five.
02
24+ months between service calls High Reliability
Marine-grade housings, sealed connectors and antifouling-ready optics survive multi-year deployments in salt, surf and silt.
03
One ecosystem, end-to-end Complete Integration
Sensors, telemetry, edge logging and cloud dashboards ship as one stack — no third-party glue code, no protocol mismatch.
04
Engineers in 30+ regions Global Support
Local engineers handle survey, install and calibration; remote diagnostics keep stations live across time zones.
05
Up to 40% lower than imports Cost-Effective
Engineered and assembled in-house, so you get the performance of imported instruments without the import-tier price tag.
Zenocean engineered a six-buoy network for our offshore observation program — sensors, telemetry, hosting and bulletin generation all from one team. Two years in, the stations are still reporting on schedule and the data center has handled every monsoon season without an outage.
