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

• Exceptionally easy to use
• WiFi recording control and file transfer capabilities.
• Up to 24-bit/96kHz sample rate and 45kHz bandwidth
• Up to 16.5 days continuous recording time: 8x longer than original μRUDAR™.
• BWF file format for easy editing and analysis using SpectraPLUS software
• Threshold-triggered recording feature
• Selectable file size rollover from five minutes to one hour
• Hydrophone sensitivity of -169dB, re. 1V/μPa
• 100m depth rating
