China Sound Velocity Profiler

Sound velocity is one of the most important hydrological parameters. Measuring accurately the sound velocity is the basis of range finding precisely by means of any sonar, e.g., depth correction of SBE, beam-angle correction of MBE and the sound ray curvature correction.
The HY1200 and HY1201 are both SVPs which employ the cost-effective "sing-around probe" technology and directly measure the velocity of sound in water. Temperature and depth where the transducer is located on for calibrating sonar systems and other acoustic instruments can also be acquired. The HY1200 and HY1201 SVPs are extensively used in the fields of hydrography, oceanographic survey, military and defense, etc.
The HY1201 is an updated SVP based on HY1200. Both of them configure a type of direct reading SVP which includes cables and a type of self-recording SVP which can store 4000 sets of data.
