Wholesale ULAR200 Ultra-Low Power Self-Contained Acoustic Recorder Manufacturer and Supplier

ULAR200 Ultra-Low Power Self-Contained Acoustic Recorder

The ULAR200 series consists of ultra-low-power, self-contained underwater acoustic sensing devices. Featuring embedded low-noise signal processing modules and utilizing piezoelectric sensing technology, these devices enable the simultaneous acquisition of underwater acoustic signals and depth/temperature data, as well as long-duration, autonomous recording. The devices’ self-noise levels are lower than those of Sea State 0 conditions; furthermore, their ultra-low-power architecture ensures stable and reliable operational endurance. The series supports synchronized multi-device array deployment—achieving synchronization accuracy superior to 1 μs—with array apertures capable of covering the full ocean depth.
