How to Use
Advantage
Traditional standard hydrophones must be connected to signal processing circuits, such as preamplifiers and data acquisition cards. The signal must be processed before it can be transmitted to the computer software, which involves the use of other equipment, software writing, etc., and the use process is more complicated; The digital hydrophone produced by our company, the signal processing circuit part is directly integrated into the hydrophone part, supporting the corresponding data acquisition software, the user only needs one digital hydrophone and one computer, greatly simplifying the hydrophone using procedures and the number of equipment, reducing the difficulty of underwater acoustic data acquisition.
