August 11, 2003—Onset Computer Corp., a provider of battery-powered data loggers, has unveiled the HOBO U12 Family—four new high-resolution, high-accuracy data loggers for measuring temperature, relative humidity, light intensity, and other indoor environmental conditions. They offer a variety of new features:
- 12-bit resolution, which provides high-resolution measurements for detecting greater variability in recorded data.
- High-precision sensors, which enable long-term data accuracy.
- Direct USB interface, which enables high-speed data offloading.
- 43K measurement capacity, which increases the amount of data that can be stored prior to being offloaded.
U12 loggers also feature a new rugged enclosure for enhanced product durability, and external input models accept the same wide range of external sensors and input cables as the company’s HOBO H8 loggers, including External Temp, AC Current sensors, and 4-20 mA and DC Voltage cables.
Typical applications for HOBO U12 data loggers include HVAC performance troubleshooting, indoor air quality and comfort monitoring, storage monitoring, and energy studies.
For data plotting and analysis, Onset offers its new easy-to-use GreenLineT software package. GreenLine enables users to launch and readout U12 loggers with point-and-click simplicity, and offers real-time monitoring capability on a PC. The software also offers a number of other convenient features, such as one-click conversion of data for easy upload into Microsoft Excel software, and the ability to view multiple channels from a single logger on one graph.
