We Make the Instruments That Measure the Ocean
Oceantek designs and manufactures ADCPs, DVLs, and hydrophones from our Hangzhou facility — in-house transducer fabrication, titanium machining, and ISO-certified production. Deployed by hydrographic agencies, offshore operators, and research institutions in 100+ countries.

Manufacturing
We Don't Just Design. We Build.
In-house control over the four processes that determine instrument quality — from raw
ceramic to calibrated unit.
Transducer Fabrication
Piezoelectric ceramic element assembly, acoustic matching layer application, and beam pattern validation — all done in our transducer lab. This is the core acoustic engine of every ADCP and DVL we ship.
Titanium Alloy Machining
CNC machining of titanium alloy pressure housings in our own workshop. Every housing is pressure-tested before assembly — from shallow-water transducer bodies to full-ocean-depth DVL casings.
Assembly & Integration
Each instrument is assembled by a dedicated technician — electronics integration, transducer mounting, connector sealing, and firmware loading. Single-unit traceability from components to serial number.
Calibration & Wet Testing
Every ADCP and DVL is wet-tested in our calibration tank or test pool before shipment. Beam alignment, velocity accuracy, and bottom-track lock are verified — not sampled, not spot-checked.
The Engine That Drives Us
Our core R&D team — 40 engineers with 80% holding master’s or doctoral degrees in acoustics, oceanography, signal processing, and electronic engineering — is the reason we can offer Tier-1 comparable performance at manufacturer-direct pricing.
We don’t license third-party transducer designs or outsource signal processing. Every beam-forming algorithm, every acoustic matching layer, every firmware module is developed here.
- Self-developed broadband & phased-array transducer technology
- Proprietary acoustic signal processing and Doppler estimation algorithms
- Ongoing collaboration with oceanographic research institutes
- Continuous investment in new frequency bands and form factors

Quality
How We Ensure Every Unit
Three-stage quality control. 100% of instruments wet-tested. This is non-negotiable.
Incoming QC
Every component — ceramic elements, PCB assemblies, titanium blanks, cables — is inspected and logged before entering the production floor. Bad parts never reach assembly.
In-Line Testing
Battery-powered autonomous recording forweeks to months. 75-PA4 in Self-Containedconfiguration is the deep-ocean standard.
Final Wet Test
Every completed instrument is deployed in our in-house test pool. Beam alignment, bottom-track lock, velocity accuracy, and full-system diagnostics — verified on 100% of units before packing.
Certifications & Honors
Certified. Audited. Recognized.
Independent verification of our quality system and technology — available to customers and distributors on request.
ISO 9001:2015
Our quality management system is certified to ISO 9001:2015, covering product design, manufacturing, assembly, and calibration. Audited annually by an independent certification body — the certificate applies to the full production chain, from incoming component inspection to final wet-test before shipment.


30+ Invention Patents
Over 30 invention patents protect our core technologies — piezoelectric transducer design, acoustic beam forming, Doppler signal processing, and pressure-housing engineering. These are granted patents, not applications — independent evidence of a self-developed product line, not an assembled one.

Where Our Instruments Go
From national hydrological networks in West Africa to offshore wind metocean campaigns in Southeast Asia, from deep-water mooring arrays in the Middle East to AUV pipeline surveys in Latin America — Oceantek instruments are deployed across six continents, supported by a growing network of trained local distributors.
