The TC4043 Miniature hydrophone offers a wide frequency range from 2Hz to over 160kHz. The frequency response is flat from 2Hz to 100kHz. The hydrophones directivity is typically omnidirectional up to 100kHz. The TC4043 incorporates a high quality 10dB low-noise preamplifier that provides optimal conditions for signal transmission over long cables. This preamplifiers features an insert voltage calibration circuit allowing the hydrophone to be reliably tested. The hydrophone is supplied with an integral 10m for conductor shielded cable. The cable is terminated with a four pole LEMO connector.
