  • Description

Description

The WiSens CTD series measures Conductivity, water depth and temperature logging across a comprehensive spectrum of marine, freshwater, and deep-sea environments. Salinity and sound velocity are calculated values. These autonomous data loggers combine robust mechanical integrity with a streamlined user experience, replacing traditional cabled instruments with an embedded Wi-Fi and web interface. Designed for oceanographers, hydrologists, and environmental researchers alike, the WiSens-CTD series scales from shallow coastal deployments to extreme deep-ocean exploration. Operators can easily configure sampling regimes, trigger conditions, and retrieve heavy datasets (CSV/ZIP formats) wirelessly using any smartphone, tablet, or laptop.

Features

  • Embedded Wi-Fi Access: Connects natively to any web-enabled device running iOS, Android, Windows, or macOS without the need for proprietary software.
  • Magnetic Activation Switch: Triggers internal wireless transmission safely while the device remains completely sealed and deployed.
  • High-Capacity Flash Memory: Internal solid-state memory securely buffers up to 2 million individual measurements across flexible user-defined sampling intervals.
  • Long-Term Deployment Autonomy: Powered by user-replaceable high-capacity lithium D-cells capable of supporting continuous, unattended operation for several years.
  • Integrated Anti-Fouling Protection: Incorporates a replaceable copper-based sensor guard explicitly designed to mitigate biological growth on the conductivity cell.

Specifications

 

Model Depth Range Conductivity Range Key Applications
WiSens-CTD-300M 300m 0-10 ms/cm (Fresh Water)
0-70 ms/cm (Sea Water)
Coastal shelf studies, mid-depth oceanography

The WiSens-CTD series does not account for any changes in atmospheric pressure during logging. Therefore, you may also require a nearby Barometric Pressure Logger to get accurate Depth readings. The Leveline-Baro Logger is an ideal option that can be located up to 10Km away.
