PORTLOG
The RainWise Portable
Weather Logger
Developed for measuring and recording in remote areas, the RainWise Portable Weather Logger
(PORTLOG) operates as a completely self contained system. No power is required. The solar/battery supply
will power the system continuously anywhere in the contiguous United States. The record rate is user
selectable from once a minute to once an hour. The 128K non-volatile RAM will store over one year of data
at a one hour record rate. Windows™ based data retrieval software is provided for downloading stored data.
The logger with all sensors, a battery charger, compass and a ten foot rugged tripod are all contained in a
sturdy lockable shipping case. All the sensors are traceable to NIST. The PORTLOG can be completely set
up and made operational by one person in less than 3 minutes.
The PORTLOG will measure and record:
Wind Speed
Wind Direction
Temperature
Relative Humidity
Dew Point
Barometric Pressure
Solar Radiation
Rainfall
The PORTLOG is guaranteed for five years.
