WM-350
The first wind meter with a
humidity sensor that never needs calibration, the extensive features of this
unit make it the first choice for outdoor professionals as well as rifleman,
the military and the sophisticated weather watcher. The wind vane allows
your readings to clearly come from the axis of the blowing wind and the
jackknife case ensures accuracy by keeping the user’s hand away from the
sensors. It is equipped with a backlight and digital compass, which also
computes cross, head/tail wind readings. Powered by a long lasting
replaceable lithium battery, the WM-350 is accurate to within 3%. Each
unit is water resistant, shock resistant, has a tripod fitting, auto shutoff feature,
weather forecast, storm alarm, clock w/date and alarm, 48 hour history graph
function, lanyard, plus a 2-yr warranty. The WM-350 has a unique data log
system with customizable record increments and an adjustable history graph.
