We are dedicated to the professional field of underwater acoustics technology. Tiandun is a national high-tech enterprise integrating R&D, production, and service. With over two decades of continuous and in-depth expertise in acoustics, we have become a significant force for innovation in the industry, committed to providing precise "hearing" and "communication" capabilities for the underwater world.

We independently master the entire technology chain, from core components such as hydrophones and underwater acoustic transducers to system equipment, including acquisition systems, acoustic release devices, underwater acoustic communication devices, OBS seismometers, and submarine towing cables, thereby possessing one-stop R&D and delivery capabilities.

We have established solid strategic partnerships with several top universities and research institutions, including the IOA, CAS（Institute of Acoustics, Chinese Academy of Sciences）, and Harbin Engineering University, ensuring cutting-edge technology and innovative momentum.

As a national high-tech enterprise, our products and solutions strictly adhere to high industry standards.

Based on this, we provide reliable solutions for key areas:

· Marine Resources and Engineering: Supporting oil and gas exploration, seabed mapping, marine engineering, and underwater infrastructure monitoring.

· National Defense and Security: Applied to underwater target detection, security, and other critical technology areas.

• Scientific Research: Serving research in marine acoustics, geophysics, and underwater acoustics.

• Environment and Monitoring: Covering underwater noise monitoring, hydrological surveys, and ecological research.

The goal of Tiandun is to become the most trusted partner for its clients. We not only provide one-stop, high-quality product sourcing capabilities but are also committed to offering in-depth, professional technical support to provide clients with a solid guarantee in addressing complex underwater challenges.
