M351 Hydrophone Field Calibrator
The M351 provides a cost-effective in-field capability for the test and calibration of hydrophones prior to deployment, ensuring accurate data collection and reducing operating costs. The battery-operated system displays the hydrophone sensitivity and/or the calibration chamber sound pressure level (SPL) on a convenient and intuitive interface.
The M351 is designed as standard to calibrate GTI hydrophones, and can be easily customized to support products from other manufacturers via custom interfaces. Communication with the unit is achieved serially via a USB-B port.
