BOURNE, MA, June 8, 2006 —Onset Computer Corporation, a leading supplier of battery-powered data loggers for outdoor andHOBO Data Logging Rain Gauge underwater monitoring applications, today introduced the HOBO® RG3, a new rainfall data logging system that combines a data logging rain gauge with a built-in data logger.

The new HOBO RG3 system enables agricultural researchers, growers, storm water managers and others to record rainfall data right out of the box without having to purchase and integrate multiple components. It records data with each tip of the rain gauge bucket – ideal in situations where peak rainfall rates need to be determined – and an internal temperature sensor enables the logger to be used in a solar radiation shield to measure temperature. Other features include:

Convenient data offload
The HOBO RG3 offloads data to a PC via a convenient optical interface, which provides high-speed, reliable data offload in wet environments.~ Its optical design eliminates the need for failure-prone mechanical connectors found in traditional outdoor data logging products.

Large memory
The HOBO RG3’s data logger offers twice the memory of previous versions, enabling users to record up to 160" of rainfall data with a 0.01 inch rain gauge. Additionally, because rainfall data is stored as rain gauge "tips," memory is not used up during periods of no rain.

Data shuttle compatible
The RG3 system works with Onset’s new HOBO Waterproof Shuttle, which allows users to conveniently offload data loggers in the field and safely transport the data back to a PC or Mac for analysis.

For plotting and analyzing rainfall data, Onset offers HOBOware® software, a highly intuitive graphing and analysis software package for PC and Mac computers. HOBOware provides a user-friendly graphical user interface and enables users to quickly and easily view rainfall per hour, day, or month, and export data to spreadsheet programs.

The HOBO RG3 Rainfall Logging system is currently available. The optic-USB base station, HOBO Waterproof Shuttle, and HOBOware software are all priced separately.
