HOBO Dissolved Oxygen Data Logger

Overview

Measure oxygen concentrations in lakes, streams, rivers, estuaries, and coastal waters with the HOBO U26 Dissolved Oxygen Data Logger. This affordable and precise data logger is recommended for aquatic biology and hydrology research projects. The HOBO U26 uses RDO Basic (Rugged Dissolved Oxygen) optical DO sensor technology and is easy to maintain.

Includes:

• U26-001 data logger
• DO sensor cap
• Protective Guard
• Calibration Boot with sponge

Highlighted Features

• Affordable, high performance dissolved oxygen (DO) monitoring with 0.2 mg/L accuracy
• Optical DO sensor technology for long-lasting calibration with less maintenance
• HOBOware Pro's Dissolved Oxygen Assistant software corrects for measurement drift from fouling; provides salinity-adjusted DO concentrations and percent saturation
• Optical USB interface for high-speed, reliable data offload
• Easy-to-replace DO sensor cap lasts six months

NOTE: For DO measurements in saltwater, an adjustment for salinity is required. For waters with small changes in salinity (<2 ppt), a salinity meter reading typically provides enough accuracy. For environments with greater salinity changes, we generally recommend the HOBO U24-002-C conductivity logger . If you need DO in Percent Saturation, barometric pressure data is required, which can be logged with a HOBO Water Level Data Logger.
