Onset today announced the HOBO U20L Series, research-grade data loggers for continuous water level and temperature measurements in streams, lakes, saltwater estuaries, and other underwater environments.
The loggers combine 0.1% measurement accuracy, a polypropylene housing for use in both fresh and saltwater, and a non-vented design for convenient and hassle-free deployment. Available in 13-, 30-, and 100-foot depth models, the loggers will be used in a range of environmental monitoring applications, from ecology studies to hurricane storm surge monitoring.
“We are all having to do more with less these days, the HOBO U20L logger’s will enable users to get more measurements throughout the spatial area they are evaluating,” said Paul Gannett, product marketing manager for Onset. “And, they will be able to maximize their project dollars without compromising on performance.”
Unlike traditional water level loggers, which rely on cumbersome vent tubes and desiccant packs for operation, HOBO U20L Water Level Loggers operate as stand-alone units. This simplifies deployment and eliminates many of the maintenance issues associated with vent tube-based loggers.
The HOBO U20 logger also features Onset’s Optical Interface, eliminating issues associated with failure-prone mechanical connectors, and it’s compatible with Onset’s HOBO Waterproof Shuttle for safe, convenient data offload in the field.
To analyze and plot water level data, Onset offers HOBOware, a highly intuitive graphing and analysis software package. HOBOware provides a user-friendly graphical user interface, and offers a number of convenient features such as a Barometric Compensation Assistant, which enables easy pressure-to-level conversion. The software also features a Bulk Export tool that allows users to export data files to text format for use in spreadsheets.
