Piezo Hydrophone 4Hz(YS-25-4Hz) 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-25-4Hz 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.
