Domestic digital hydrophone

The domestically produced digital hydrophone LST-DH01 is a new type of underwater acoustic signal acquisition device that integrates amplification and conditioning circuits, acquisition, storage, and digital transmission. The digital cable can reach up to 70 meters and has a standard USB interface, making it very convenient to connect to computer systems. Due to the elimination of complex equipment such as preamplifiers, filters, and collectors that are necessary for using hydrophones, the system's reliability and anti-interference performance have been improved. It has the characteristics of low background noise, large dynamic range, high acquisition accuracy, and provides both sound pressure value and relative sound pressure level, making it convenient for users to quickly form a noise measurement and observation processing system.
