Product Summary
The Wireless Optical Dissolved Oxygen (ODO) Sensor is ideal for monitoring DO2 in the lab or field. The Wireless Optical DO Sensor is automatically compensated for temperature and pressure when reporting values. The optical technology is accurate, fast, and does not require stirring, filling solutions, warm-up, or frequent calibration. When equipped with the included cover, the sensor has a waterproof design and is submersible to a depth of 10 m.
A PASCO exclusive feature allows you to log data using the sensor's built-in memory. After collecting data for hours or even days, simply connect the sensor to your device and you're ready to download your data. With this powerful sensor, educators can explore day and night nutrient cycles, changes in metabolic processes, seasonal changes in water quality, and more.
Applications
- Teaching field sampling techniques
- Exploring how temperature influences dissolved oxygen concentrations
- Measuring net primary productivity
- Modeling ecosystems
- Monitoring water quality and investigating watersheds
- Investigating photosynthesis and cellular respiration in aquatic environments
What's Included
- 1x USB Cable (for recharging and optional direct connection)
- 1x Protective cover
