Marine Hydrological Instrument
Art.No.: DW14 Series
Keywords: CTD, TD Sensor
Supplier: Qingdao Daowan Technology Co., Ltd.
Daowan DW14 Series TD is a instrument for measuring temperature and pressure (depth), with a maximum depth rating of 6000 meters. Designed for flexible deployment, it can be installed on various platforms such as seabed mounts, piers, docks, mooring systems. Daowan DW14 Series TD is available in two versions. The Direct-reading version requires external power and provides real-time data transmission via cable. The Direct-reading Self-contained integrated version features an internal battery and memory, supports real-time connection when cabled, but can also operate independently to log data for later retrieval upon recovery.
Features
Performance: Research-grade accuracy, Ultra-high resolution, Long-term stability
Structural Integrity: Titanium alloy shell, Pressure tolerance up to 6000 dbar
Interoperability: Simple for integration with other instruments or platforms
