Teledyne RD Instruments, Inc., located in Poway, CA, specializes in the design and manufacture of underwater acoustic Doppler products for a wide array of current profiling and precision navigation applications.

The company was originally founded as RD Instruments back in 1982 through the development of the industry's first Acoustic Doppler Current Profiler (ADCP^TM), a revolutionary device capable of profiling currents at up to 128 individual points in the water column.  Over the years, this innovation has spawned a full line of high quality, versatile, acoustic Doppler products.  From the shallowest stream, to a towering offshore platform, and everywhere in between, Teledyne RDI has a proven ADCP designed to address the industry's needs.

In August 2005, RD Instruments became Teledyne RD Instruments when it was purchased by Teledyne Technologies.  Teledyne RDI now operates as a wholly owned indirect subsidiary of Teledyne Technologies, Inc., and is a member of the growing family of Teledyne Marine companies.

Teledyne RDI currently employs over 200 multi-disciplined scientists, engineers, technicians, sales, and support personnel; and resides in an 80,000 square foot ISO-9001:2000 facility that includes state-of-the art engineering, laboratory, manufacturing, and test areas.

Through market growth and product diversification, the company is divided into three distinct business units: 

Marine Measurements:
Acoustic Doppler current profiling and wave measurement products for coastal and deep water oceanographic environments.

Navigation:
Precision navigation products for the marine environment.

Water Resources:
Discharge and flow-measurement products for inland environments.

As Teledyne RDI has grown, so has their customers' need for global service and support. Recognizing this need, Teledyne RDI now operates offices in Poway, CA USA; La Gaude, France; and Shanghai, China.  The company also offer 24/7 service and support and free online weekly training seminars.

After 25 years, Teledyne RD Instruments remains the industry leader in Doppler technology, offering continuous product development, a dedicated service and support team, and a commitment to our customers' ultimate success.
