SINGLE-BEAM ECHO SOUNDER FOR BATHYMETRIC SURVEY
The CHCNAV D270 is a portable single beam echo sounder. Its water temperature sensors allow real-time correction of sound velocity based on water temperature, resulting in even more accurate water depth measurement. The echo sounder can be used for river section measurement, reservoir capacity measurement and dredging volume measurement of waterways. The two frequencies of 200 KHz and 25 Khz can be switched according to the water quality, in order to optimize accuracy and adapt to the measurement environment. The D270 features an easy and intuitive configuration and map display web page through a simple connection to a smartphone.
