Hydrophone Calibration System Type 9718 is a customer configurable system for calibration of underwater transducers both at the secondary and primary level.

The system is built around the Brüel & Kjær PULSE multi–function analyzer with a 2–channel 200 kHz acquisition module and controlled by a dedicated calibration software package.

The system allows you to perform free-field frequency response calibration of hydrophones in accordance with EIC 60565 in the frequency range from a few kHz up to 200 kHz, both receiving and projecting response in possible.

The lowest usable frequency depends on the size of your acoustic tank. Typically, a tank size 5 x 5 x 5 m will allow calibration down to approximately 3 kHz.
