Airmar Technology Corporation stands at the forefront of ultrasonic and acoustic sensing innovations. Our advanced marine transducers redefine ultrasonic technology, enabling extraordinary surveying capabilities even at meaningful depths.These transducers are perfectly suited for unmanned surface vehicles (usvs), autonomous underwater vehicles (AUVs), and unmanned ground vehicles (UGVs).
Additionally,we offer robust and compact ultrasonic weather stations that provide precise measurements of wind speed,temperature,pressure,and humidity. These stations are designed for various applications, including fixed land and marine sites, deployable stations, and dynamic platforms like USVs, ASVs, and UGVs.

- Underwater Altimeters & Ultrasonic Depth Sensors
- Single & Multi-beam Marine Transducers
- Side-Scan Sonar Transducers
Weather Monitoring Stations
Our durable ultrasonic weather stations provide high-precision measurements of wind speed and direction, air temperature, and barometric pressure. Some models also include features for relative humidity, multi-axis compasses, pitch and roll, and GPS positioning. These low-maintainance units are straightforward to install and come with IPX4, IPX6, or IPX7 ratings for protection against the elements.
The product range caters to both fixed-site installations, such as UAV ground control stations and vessel launch areas, and mobile marine platforms like USVs and ASVs.

Underwater Altimeters & Ultrasonic Depth Sensors
Our ultrasonic EchoRange Smart Sensors deliver precise underwater temperature and depth readings, making them ideal for applications like inspection and hydrographic surveying. They transmit NMEA 0183 data in real-time to a computer via RS-422. The EchoRange+ models also feature bi-directional NMEA 0183 interfaces and an OEM-exclusive Echo Envelope Developer Option, allowing users to access detailed echo envelope data, which can be visualized as an analog waveform to reveal seafloor characteristics.
We also provide an altimeter kit designed for AUVs, ROVs, and marine robotics. This kit includes a compact transceiver board for integration into the vessel’s electronics and a separate underwater transducer. The subsea altimeter can be configured for manual or fully automated sounding modes.
