The POEMS-A developed by High Tech, Inc. is a highly portable, autonomous acoustic measurement system. The system combines many hard to find features in a single, compact instrument.
The system was specifically designed to be used with the High Tech, Inc. HTI-92-WB low-noise, wide band hydrophones. The hydrophone array incorporates a proprietary encapsulation process to prevent leakage to seawater. Custom signal conditioning circuit boards have been designed and built for the 24 acoustic channels. Programming and control software for controlling system operation through High Tech Inc.'s custom controller card are included with the system. No software development by the customer is required.
