Description

The WiSens DO series measures Dissolved Oxygen, depth and temperature logging across a comprehensive spectrum of marine, freshwater, and deep-sea environments. 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-DO series scales from shallow coastal deployments to deep-ocean exploration with optional wiper to clean the sensor and bio-fouling build-up. 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.

Model Depth Range O2 Concentration O2 Saturation
WiSens-DO-30M 30m 0-23mg/l (Max 0-44 mg/l) 0-250% (Max 500%)
WiSens-DO-300M 300m 0-23mg/l (Max 0-44 mg/l) 0-250% (Max 500%)
WiSens-DO-1000M 1,000m 0-23mg/l (Max 0-44 mg/l) 0-250% (Max 500%)

The WiSens-TBD 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.
