The RainWise MK-III-RTI-LR wireless long range transmitter for weather stations combines all outside sensor components into a single compact unit that's easy to install. With a transmission range of over one mile line of sight, this weather station is a great choice for applications where remote conditions must be monitored from outside of the 400 foot range of standard models.

The RainWise Weather Oracle multi-display (sold separately) permits viewing all weather variables simultaneously or you can customize the display, showing only those parameters you select. You have choices on brightness, as well as to wall mount or place free-standing on a table or shelf. This unit comes in four different frame types: black, cherry, or mahogany wood, and black metal.
