Marine Hydrological Instrument
Art.No.: DW16 Series
Keywords: CTD
Supplier: Qingdao Daowan Technology Co., Ltd.
DW16 Series is a professional CTD hydrological observation instrument which can measure the parameters of conductivity, temperature, pressure (depth) and calculate the data of salinity, density and sound speed. DW16 Series offers Direct-reading or Direct-reading Self-contained integrated modes for different types of integrated systems or profiling systems. It is capable of working reliably at a depth of 6000 meters. The DW16 standard packages include user-friendly software and cables, offering a simplified and efficient solution for research, monitoring and engineering applications.
