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!
