RainWise MK-III-RTN
MK-III-RTN Weather Station without Rain Gauge

The model MK-III-RTN RainWise wireless weather station includes all of the sensor components found on the MK-III-RTI, except for the rain gauge.

The RainWise Weather Oracle multi-display 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.

If you require a longer range system, the MK-III-RTN-LR transmits over one mile, line of sight!

Note: We do carry a magnetic compass to help you orient your anemometer to true north. For more information on set up, please visit the anemometer page on our WeatherShack education center.
