Temperature And Depth Probe DW14
Category: CTD
Art.No.: DW14 Series
Keywords: CTD, TD Sensor
Supplier: Qingdao Watertools Technology Co., Ltd.
Introduction:

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 self-contained 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.
