WEATHER STATION The PORTLOG will measure and record: Wind Speed Wind Direction Temperature Relative Humidity Dew Point Barometric Pressure Solar Radiation Rainfall The non-volatile memory can provide data storage for up to 9 months at a one-hour logging rate. The user selectable rate can be adjusted down to one minute. Memory upgrades are available for extended logging applications. The PortLog memory can be configured to wrap or stop logging when full. In wrapping mode, the oldest record is replaced with newest when the memory if full. Wind speed records include peak and average speeds for the interval. The average direction is recorded. The remaining parameters are instantaneous readings. Data is output in comma-delimited text (CSV). Microsoft Excel can be used to view, graph and manipulate the data. The PortLog features a patent pending wind direction sensor that provides 1-degree resolution with no dead band. The wind speed sensor features race bearings, which offer excellent longevity and a low starting threshold. The precision barometer reports absolute atmospheric pressure but can be corrected for altitude. Corrections are made using the supplied software. Data can be retrieved from the PortLog using a notebook computer, Windows Mobile PDA (with PLmobile software), landline modem or cellular modem. An additional power source will be required to power communication equipment. Includes: Solar powered sensor/data logger assembly Battery charger Compass Ten-foot tripod Tie down hardware Software and RS-232 cable Carrying case.
