The PortLog is a compact rugged industrial grade data logging weather station. The unit is fully assembled and can be quickly deployed. The large 3-Watt solar panel and 4AH sealed lead acid battery ensure reliable operation in the harshest conditions.
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.
