Product Description
The HOBO U26-001 Dissolved Oxygen Data Logger measures concentrations of dissolved oxygen in lakes, streams, rivers, estuaries, and coastal waters. Used by aquatic biologists, hydrologists, and other research professionals to monitor water quality, the U26 is ideal for climate change and environmental impact studies as well as ecological and oceanographic research.
The HOBO U26 combines the high-accuracy, robust performance of industry-leading RDO® Basic (Rugged Dissolved Oxygen) optical sensor technology with an easy-to-maintain design, all at a fraction of the cost of other monitoring options. The optical DO sensor technology provides accurate measurements without the maintenance requirements of traditional electrochemical sensors.
Measurement range: 0 to 30 mg/L with accuracy ±0.2 mg/L and resolution 0.02 mg/L. Stores 21,700 sets of DO and temperature measurements at logging rates from 1 minute to 18 hours.
