DO-1000L – Logging dissolved oxygen sensor

The DO-1000L is a logging dissolved oxygen sensor. The internal logger provides a compact design ideal for long-term deployment in the field. The sensor can also be powered by onboard batteries which will provide up to 6 months of data logging. The battery packs will negate the need for solar panels or other external sources of power.

DO-1000L features:
  • Can be installed in active waters (acidic or salty conditions)
  • Reliable and robust sensor ensures minimal servicing visits
  • Suitable for marine applications and waterways with high sediment loads
  • Easy to configure logger – quick retrieval of data using SensorMate software
  • Graphical and tabular display – export to spreadsheet format
  • Standalone operation with on board battery Pack
  • Various cable options for telemetry and integration applications
