The model MK-III-RTN RainWise wireless sensor array includes all of the sensor components found on the MK-III-RTI, except for the rain gauge. If you require a longer range system, the MK-III-RTN-LR transmits over one mile, line of sight!
The wireless, rugged outdoor sensor array runs completely on solar power. The MK-III solar charged battery supply is guaranteed to provide continuous operation below 60 degrees latitude and will operate for at least 60 days without sun.
Unless you're purchasing the unit as a replacement, the MK-III-RTN sensor array requires a RainWise Display and/or the optional Computer/Network Interface. The sensor array can broadcast weather data to multiple displays, computers or network interfaces. The sensor array transmits a packet of data every two seconds offset by 30 seconds.
Note: We do carry magnetic compasses to help you orient your anemometer to true north. Those can be located under the "Accessories" tab. For more information on set up, please visit the anemometer page on our WeatherShack education center.
