Hydrophone 5Hz

Hydrophone 5Hz(YS-25-5Hz) are low frequency piezoelectric sensors for prospecting purpose in swamp, transition zone, river and shallow sea. The product is small size, stable and high sensitivity for output and non-directional receiving. Its high temperature injection molding seal structure makes it better for water proof and its tail suspension wire’s design makes it more suitable for field wiring.

The YS-25-5Hz hydrophones are entirely molded polyurethane units that eliminates water leakage and also prevents water from migrating down the cable into the body of the hydrophone.

● Hydrophone Cable: Water blocked cable, O.D.7.8mm to 12.5mm.

● Waterproof Connector: 408 Style ULS Cable Connector, Screw Fit KCK Connector, Screw Fit KCL Connector,NK27 System Connector or Bendix Style 61 Pin System Connector for Geode Seismograph are optional.

● Cable Length: 1m, 3m, 5m, 10m or Custom Length as per Clients’ Request.

●  6 / 12 / 24 / 48 Channel Hydrophone Cable Steamer are Available as per client’s customized requirements.
