February 13, 2004—Onset Computer Corporation, producer of battery-powered data loggers, has added two new models to its line of HOBO U12 high-resolution, direct-USB data loggers. The new loggers accept up to four external sensors for measuring AC current, 4-20mA, DC voltage, temperature, and Carbon Dioxide (CO2). Onset says this enables FMs, HVAC contractors, energy managers, and maintenance technicians to easily and affordably solve a broad range of indoor and outdoor energy, HVAC, and industrial monitoring applications, including:
- Energy audits;
- Building commissioning;
- IAQ studies;
- Temperature set-back strategies;
- Comfort complaints; and
- HVAC/R systems troubleshooting.
To plot and analyze data recorded with HOBO U12 loggers, users can choose between Windows and Macintosh-based software options. GreenLine software (for Windows) and HOBOware software (for Macintosh) enable users to launch and readout U12 loggers with point-and-click simplicity, and offer other convenient features such as one-click conversion of data for easy upload into spreadsheet applications, and the ability to view multiple channels from a single logger on one graph.
The new HOBO U12-006 4-channel indoor and U12-008 4-channel outdoor/industrial loggers are priced at $119 and $199, respectively, and are available now. Greenline and HOBOware software packages are priced at $59. For more information or to order, visit Onset Computer Corporation.
