Dissolved Oxygen Probe
Recommended for College and High School. Interface and software sold separately.
Use the Dissolved Oxygen Probe to determine the concentration of oxygen in aqueous solutions in the field or in the laboratory.
Description
The Dissolved Oxygen Probe is great for biology, chemistry, ecology, or integrated science courses. It can be used to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the primary indicators of the quality of an aquatic environment.- Built-in temperature compensation lets you calibrate in the lab, then make measurements outdoors without having to recalibrate.
- Disposable caps with pre-fit membranes allow you to quickly and conveniently change membranes.
- Calibrate in the units you choose: % dissolved oxygen, mg/L, or ppm dissolved oxygen
Specifications
- Range: 0 to 15 mg/L (or ppm)
- Accuracy: ±0.2 mg/L
- Response Time: 95% of final reading in 30 seconds, 98% in 45 seconds
- Resolution: 0.014 mg/L (LabQuest 2, LabQuest, LabQuest Mini, Go!Link, LabPro)
- Temperature Compensation: automatic from 5–35°C
- Pressure Compensation: manual
- Salinity Compensation: manual
- Minimum sample flow: 20 cm/second
