µRUDAR U/W Signal Recorder

µRUDAR Autonomous Underwater Signal Recorder

Extended Life (up to 16.5 days) micro Remote Underwater Digital Acoustic Recorder (µRUDAR)

The Cetacean Research™ µRUDAR-mk2™(micro Remote Underwater Digital Acoustic Recorder) is a very compact, short-term, autonomous recording device that is designed for fast and easy deployment in a wide range of applications.

Uses of the  µRUDAR-mk2™ range from remote detection of methane bubbles to recording wild cetacean vocalizations for periods of more than sixteen days.

This easy-to-use recording system can be deployed to depths of up to 100m and will provide more than 5 days of continuous 24-bit, 96kHz sample-rate data acquisition, and up to 16.5 days at 16-bit/44kHz sample-rate.

As with the  nRUDAR-mk2™, the µRUDAR-mk2™ also have the capability to control recording transport and file transfer via WiFi from a smart phone or tablet app.

The  µRUDAR-mk2™ uses the same hydrophone element and preamplifier as our Sensor Technology SQ26-08 hydrophone along with a 24-bit, 96kHz digital recorder.
