Model ITC 8201 A
Low Noise Differential
Output Hydrophone
The Model ITC-8201 has a differential output with a very low noise preamplifier. Al-
though polyurethane encapsulated, this hydrophone maintains its low frequency roll-off
over long-term deployments through an improved internal insulation technique. It can
drive cable lengths up to 2,500 feet.
