The HOBO® U26 Dissolved Oxygen datalogger records dissolved oxygen concentration and water temperature with high precision and reliability. It uses an optical sensor that ensures long-term stability and eliminates accuracy drift over time.
The free HOBOware® software, available for Windows and Mac, allows you to download, visualize, and configure all instrument parameters such as date and time. Communication with the computer is done through the universal optical USB base station BASE-U-4 or the U-DTW-1 shuttle (not included).
Designed for harsh aquatic environments, the datalogger features a compact and corrosion-resistant construction that ensures long-term durability. The included lithium battery provides an extended operational lifespan before replacement is needed.

These high-precision conductivity data loggers are a cost-effective way to collect water quality data. The HOBO U24-001 data logger records both conductivity and temperature measurements in streams, lakes and other freshwater sources. This data logger is recommended for monitoring aquifers for saltwater intrusion and runoff from roads or agricultural land.
The HOBO U24-002-C is a cost-effective data logger for measuring salinity, conductivity and temperature in saltwater environments with relatively small changes in salinity (± 5,000 µS/cm), such as saltwater bays, or for detecting salinity events such as surges, storms or discharges. It can also be used to collect salinity data for salinity compensation of HOBO U26 dissolved oxygen data.
This open-to-its-sensor product simplifies cleaning and maintenance. The non-contact HOBO sensor minimizes measurement errors related to changes. In addition, the data loggers feature software-based shift compensation.
It works in outdoor and underwater environments.
Supports conductivity/salinity and temperature.
Note: When monitoring salinity in waters with more than +/- 5,000 µS/cm variation, refer to the accuracy shown in Plot C in the product specifications to determine if the accuracy is acceptable for your needs. Monthly field calibration readings are generally required to achieve the best accuracy.

The dissolved oxygen sensor is an interchangeable sensor that works with HOBO MX800 Series Water Loggers to measure dissolved oxygen and temperature.
The DO sensor can be attached directly to the fully submersible MX801 model, or attached via cable to the direct read MX802 model, which doesn’t require having to pull the sensor out of the water to download data.
When this sensor is connected to a HOBO MX800 logger that also has a conductivity or CTD sensor attached, the logger can record salinity-adjusted DO directly. With this sensor attached to the HOBO MX802 direct read model, the logger can calculate DO percent saturation directly. When used with fully submersible HOBO MX801 model, a barometric logger data file (from either an MX802 or MX2001 logger) is needed to calculate DO percent saturation, for post-processing in the HOBOconnect app. In waters with changing salinity, the logger must also have a salinity sensor attached or you will need an MX800 salinity data file to get DO percent saturation.
