Looking for hydrographic or oceanographic equipment? Apart from our survey vessels we have a range of equipment available for rent.

Profiling Current meters

Teledyne Workhorse Monitor ADCP 1200 kHz, 600 kHz & 300 kHz

The MONITOR is Teledyne RD Instruments’ most popular direct reading Acoustic Doppler Current Profiler (ADCP). The Monitor offers a choice of three frequencies and ranges, to meet a wide array of data requirements. The unit also offers a flexible upgrade path, which includes an external battery pack, pressure sensor, bottom tracking capability for moving boat applications, and directional wave measurement.

RiverPro 1200 kHz

The 1200 kHz RiverPro has been purpose-built to fill two specific needs:

  • To provide an ADCP designed specifically for shallow river applications (20 cm to 25 m range)
  • To provide an upgrade path for our current industry gold-standard Rio Grande ADCP users

Like our next-generation RiverRay ADCP (see below), the RiverPro offers users a 5-beam solution, auto-adaptive sampling, user-friendly interface, and Teledyne RDI’s unsurpassed quality, service, and support. The RiverPro has also been designed to fit into our RiverRay float, allowing users to swap out their ADCPs based upon their environment, eliminating the need to purchase and transport a second float.
