The initial sensor calibrations for wind, temperature, relative humidity, and barometric pressure on the MK-III are traceable to the National Institute of Standards and Technology (NIST). The passive solar shield for the temperature/humidity sensor are based on those designed by the U.S. National Weather Service. All materials used in the sensor assembly and weather instruments are chosen for durability and resistance to weathering and corrosion. All hardware is stainless steel and the weather station is fabricated from fiberglass and ultra-violet inhibited structural PVC.
Like the RainWise model MK-III-RTI, the MK-III-RTI-LR wireless weather station combines all outside sensor components into a single compact unit that's easy to install. With a transmission range of over one mile line of sight, this weather station is a great choice for applications where remote conditions must be monitored from outside of the 400 foot range of standard models.
The large decorative and highly visible RainWise MK-III Weather Oracle multi-display provides a complete set of current weather data that's viewable anywhere in a room. You have choices on brightness, as well as to wall mount or place free-standing on a table or shelf. This unit comes in four different frame types: black, cherry, or mahogany wood, and black metal.
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.
