HOBO Dissolved Oxygen Logger Model U26-001

This precision, self-contained data logger is ideal for measuring concentrations of oxygen in lakes, streams, rivers, estuaries, and coastal waters. Because oxygen concentration is essential for healthy aquatic life, this data logger is a valuable tool for aquatic biologists, hydrologists, and other research professionals. The data logger records up to 21,700 sets of dissolved oxygen and temperature measurements, and the logger utilizes optical dissolved oxygen sensor technology for long-lasting calibration with less maintenance. The optical USB interface allows for high-speed, reliable data offload. Includes data logger, dissolved oxygen sensor cap, protective guard, and calibration boot with sponge. HOBOware® Pro software and an Optic USB Base Station (each sold separately) are required for operation. This logger is also compatible with the HOBO Waterproof Data Shuttle (sold separately), allowing for easy and reliable data transfer and retrieval.
