This sensor measures dissolved oxygen in mg/L or percent saturation, without requiring calibration or warm up time.
See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
The PASCO Optical Dissolved Oxygen Sensor makes it easier than ever before to measure dissolved oxygen in the lab or field. The luminescent technology offers several advantages over galvanic DO sensors including:
- No flow dependency – no stirring required
- No warm-up time
- No calibration required
- Low maintenance – no filling solution and electrode polishing
- Built-in temperature and pressure compensation
- Ability to measure gaseous as well as dissolved oxygen
Applications
- Photosynthesis, Respiration and Fermentation labs
- Monitoring Water Quality
- Measuring Net Primary Productivity
- Modeling Ecosystems
