HOBO UX100 data loggers for tracking temperature and humidity indoors

HOBOs take their environmental act indoors

Onset is probably best known for its line of rooftop HOBOs, which resemble small robots and can help federal and state governments, as well as private sector companies, manage their buildings more efficiently by creating green rooftops. The rooftop HOBOs also make sure that plants and grasses up on the roof are getting enough water, sunlight and nutrients.

The newest HOBO units, however, are aimed at keeping indoor environments cool and comfortable for workers, and equipment running in optimal conditions.

Onset has announced the HOBO UX100 Series, the company’s next-generation family of data loggers for tracking temperature and relative humidity in indoor environments. Starting at $75, HOBO UX100 Series loggers deliver high accuracy and large measurement capacity, the company said in its announcement. Users can easily see all of the collected data on a large LCD display.

Building owners, facility managers, energy auditors and others can use the matchbox-size UX100 Series data loggers to quickly and easily collect indoor environmental data in a broad range of applications. This includes monitoring occupant comfort in office buildings, tracking food storage conditions in warehouses, logging temperature trends in server rooms and measuring humidity levels in museums.

HOBO UX100 data loggers feature an easy-to-view LCD display that visually confirms logger operation and battery status, eliminating the need to connect the logger to a PC to see the information. A large memory capacity enables users to deploy the loggers for longer periods with fewer site visits. All UX100 loggers also feature start and stop pushbuttons. They can be mounted using magnets, straps, and command-strip mounting options.

Once data has been recorded with HOBO UX100 data loggers, it can be viewed in graph form and analyzed using Onset’s HOBOware Pro software. Time-saving tools allow users to batch-configure and read out hundreds of loggers in a fraction of the time it would take with previous generations. Additionally, the software features a Bulk Export tool that allows users to export data files to text format for spreadsheets, and is available in English, French, Spanish, Portuguese and German.

HOBO UX100 Series has five models, including temperature-only loggers with integrated sensors, temperature/RH and thermocouple loggers with external probes. Prices range from $75 to $189.
