The model MK-III-RTN RainWise wireless sensor assembly includes all of the sensor components found on the MK-III-RTI, except for the rain gauge. Unless you're purchasing the unit as a replacement, the MK-III-RTN sensor assembly requires a RainWise Weather Oracle multi-display and/or 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 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.
If you require a longer range system, the MK-III-RTN-LR transmits over one mile, line of sight!
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.
