Developed for measuring and recording in remote areas, the RainWise Portable Weather Logger operates as a completely self contained system. No power is required. The solar/ battery supply powers the system continuously anywhere in the contiguous United States. Record rate is user selectable from once a minute to once an hour. The 128K non-volatile RAM will store up to 9 months of data at a one hour record rate. Windows based data retrieval software is provided for downloading stored data.

PORTLOG with all sensors, a battery charger, compass and 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.
