DO2 Dissolved Oxygen

SENSOR WITH DATA LOGGING

Dissolved Oxygen Sensor with Integrated Datalogging
  • Measures dissolved oxygen and temperature.
  • Integrated datalogger collects over 170,000 records.
  • Utilizes fluorescence sensor technology.
  • No membranes, fill solutions, replacement caps, or cartridges required.
  • Includes new Aqua4Plus control software.

Description

Seametrics’ DO2 Smart Sensor is the next generation in trouble-free oxygen sensing design.

Utilizing fluorescence of a stable, immobilized ruthenium-based film matrix, the sensor provides precision optical transmission and detection to measure oxygen concentration in the fluid outside of the sensor.

Equipped with integrated datalogger and Aqua4Plus software, this sensor provides convenient, high-quality data to the user.
