The RainWise® MKIII-LR
Long Range Weather System
The MKIII-LR is a wireless, solar-powered weather station. It’s original version, the
best-selling MKIII, broke the price barrier in 2002 when it was released. It provides the
best accuracy of any consumer weather station on the market and includes the capabilities
and features desired by knowledgeable weather enthusiasts, with the easiest setup and
installation of any instrument being sold today.
Since then, we have worked diligently to improve the performance of the MKIII. We have
done just that with the MKIII-LR by dramatically expanding its transmission range to one
mile (LOS)*. This distance vastly surpasses other comparable weather stations on the
market, where the current long range distance is 1000 feet.
Another breakthrough feature for the new MKIII-LR is that it now transmits data every 2
seconds, without delay, so information sent to the LED display or computer interface is
virtually real-time. It uses spread spectrum radio technology. While the range may vary
due to environmental conditions (such as topography, building walls, snow, etc.), the
MKIII-LR far surpasses (by as much as 4X) any other wireless weather station in its class
and price range. It is the most accurate, reliable and easy to install weather station on
the market today.
The MKIII-LR system is available in a variety of configurations, depending on what the
- The MKIII-LR Sensor Assembly is included in every system as it collects and transmits
the data. The solar-charged battery supply is guaranteed to provide continuous operation
below 60° latitude and will operate at least 25 days without sun. The passive solar
shield for the temperature/humidity sensor is modeled after the National Weather Service
design. The solar panel and battery are guaranteed for five years. It’s sleek design
(just 5” x 6” x 27”, and under 7 lbs) belies its rugged construction. The
extension mounting mast, fabricated from 11/4” schedule #80 PVC pipe, will fit any
standard tripod or TV antenna mount.
- An attached Rain Gauge can also be included in a system.
- The Weather Oracle® multi-display can be purchased to display the Time (date),
Temperature (outside, inside, wind chill, dew point), Relative Humidity
(temperature/heat index), Barometric Pressure (rising, falling), Rainfall (current,
accumulation), Wind Speed and Wind Direction (variation). Maximums and minimums are
available to the month, day, hour and nearest minute. The display offers brightness
controls to suit the ambient lighting conditions and can be wall-mounted or placed
free-standing (a wall transformer powers the receiver). The MKIII-LR allows for multiple
peripheral use. You can have as many displays or interfaces as you wish. The only
limitation is range and power availability. The multi-display is available in an
attractive cherry, mahogany or black wooden frame.
- The MKIIICC-LR wireless computer interface records and stores weather data received
from the MKIII-LR sensor assembly. Purchase this with the multi-display or instead of.
It can be placed anywhere, as it’s not connected to the display in any way. The CC-3000 is normally shipped with a USB 2.0 interface. An RS-232 version is available for applications that require serial connections like cellular and satellite modems. The baud rate has been boosted from 9600 to 115,200. Even with extra memory download times are dramatically reduced. USB drivers are provided for Windows, Mac and Linux. Note: Only Windows based software is currently available.
Each CC-3000 is shipped with a free version of Weatherview32 V8 Home Edition. Upgrades are available.
Whichever components you choose, the MKIII-LR system offers everything you need for a
comprehensive professional or home-use weather station.
