John, Davis is a big co. that used to sell into the pro. & scientific markets. No idea re their consumer stuff. I used to make "weather stations" for micro-meterology research... and we always made our own as most commercial stuff was not "frontiers of science" type stuff...

cup anemometers are common - you will need to worry about stall speed mainly as they do not respond to low wind speeds; also 'reach' - the distance of a parcel of wind is an issue...

or you can use a propeller type; a sonic anemometer; laser doppler, hot wires, heated beads, pitot tubes... even a suspended logging chain or ping pong ball

so, what exactly are you wanting to do?

do you want to know what the climate is for a sparrow under your tree? an ant behind a leaf?

'cuz the basic weather info by good amateurs near you is fine & is on the net...

OTOH, if you want to measure total solare radiation and partition it into Short wave & long wave components, get diffuse vs. direct beam, or any micro-met. stuff.... it can be done
