Description Tech Specs
The MKIII-LR is a wireless, solar-powered weather station. Its 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, RainWise has worked diligently to improve the performance of the MKIII. RainWise has done just that with the MKIII-LR by dramatically expanding its transmission range up 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 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 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.

Its 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 wallmounted 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. 

You can choose to purchase the MKIIICC-LR wireless computer interface with the multi-display LED console or you can choose to purchase the MKIIICC-LR and view your weather data only on your computer. The MKIIICC-LR records and stores weather data received from the outdoor sensor suite. The MKIIICC-LR can be placed anywhere, but RS-232 cabling is required between the interface and your computer.

The interface has 32K of RAM which allows you to log the weather data at rates from once per-minute to once-per-hour. It will store data up to three months at once-per-hour record rates. Easy to install and use, it also includes an RS-232 cable to interface with your computer serial port. The Interface can connect to a dial-up modem, permitting remote access to locations such as camps and summer homes.

Whichever components you choose, the MKIII-LR system offers everything you need for a comprehensive professional or home-use weather station.
