This kit consists of a multi-axis bubble level device and a digital compass + altimeter.
The level enables correct multi-axis vertical orientation of a tripod or post. The weather station must be level to insure optimum sensor performance and accuracy.
The WS-108 compass (with declination) enables correct alignment of the wind direction sensor to true north.
The WS-108 altimeter includes sea-level barometer correction. By entering your altitude, the altimeter calculates the sea-level barometric pressure offset automatically.
The individual components can also be purchased below.
Note: Most Davis Instruments weather stations already include a built in level and altitude adjustment in the console, so this kit is not required.
