The dramatically expanded transmission range of over one mile line of sight is a breakthrough feature of the RainWise MK-III-RTN-LR wireless sensor assembly. This model includes all of the sensor components found on the MK-III-RTI-LR, except for the rain gauge. If rainfall measurements are not of interest to you, and your application requires a long distance between sensors and receiver, the MK-III-RTN-LR is a perfect solution.

Unless you're purchasing the unit as a replacement, the MK-III-RTN-LR sensor assembly requires a RainWise Long Range Weather Oracle multi-display and/or LR Computer Interface. The sensor assembly can broadcast weather data to one or more receivers, allowing you to have as many displays and computer interfaces in a building as you like. The MK-III-LR Weather Oracle multi-display provides a complete set of current weather data that's viewable anywhere in a room. Available in a variety of finishes, this attractive readout can be set on a table or mounted on a wall.

Note: We do carry magnetic compasses to help you orient your anemometer to true north. Those can be located under the "Accessories" tab shown above. For more information on set up, please visit the anemometer page on our WeatherShack education center.
