Dissolved Oxygen measurements are essential to water quality, Biology, Earth Science and Chemistry investigations. Our DO Sensor accommodates more applications, allowing students to explore these subjects more thoroughly. Wider range (0 to 20 mg/L) ensures the sensor does not top out before the experiment is over.

Excellent resolution (0.01 mg/L) allows students to see small changes.
Temperature compensated - essential for consistent measurements.
Easily replaced membrane cartridges maintain sensor performance.

Features

Fully Compensated Temperature at 10 °C to 40 °C

Typical Applications

Biological Oxygen Demand (B.O.D.)
Investigate how the presence of organic matter affects DO levels.
Water Quality Studies
Monitor the effects of yeast respiration on dissolved oxygen concentration

Includes
