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 the newest when the memory is 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 a 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, landline modem or cellular modem. An additional power source will be required to power communication equipment.
The PortLog will record the following parameters:
- Wind Speed
- Wind Direction
- Dew Point
- Solar radiation
All sensors are NIST traceable.
The PortLog is normally supplied with a tough carrying case. The case will carry the PortLog, tripod, and accessories. Accessories include a hammer, battery charger, and a handheld compass.
The tripod can be quickly assembled and includes a ground anchor. One person can easily deploy the weather station in a few minutes. The PortLog can also be supplied without the tripod and carrying case.
The PortLog is guaranteed for five years.
