The Speedtech Instruments WM-350 WindMate 350 Multi-Function Weather Meter! This is a prize-winning, comprehensive weather monitor, which gives full environmental data specific to your location and includes a 48-hr history for every function, hour-by-hour and in a bar graph. The USA fluxgate compass reads when held vertically, measuring not only wind direction in degrees and compass points but also calculating crosswind and head/tail wind. The compass can be calibrated for variation/declination and deviation. In addition to wind speed/direction, temperature, barometric pressure, altitude, and relative humidity, the WindMate 350 featurs wind chill, Wet Bulb, Dew Point, Delta T and Density Altitude. The Speedtech WM-350 also provides an accurate weather forecast and has an audio storm alarm that alerts you to weather changes, even if the unit is off!
The WindMate 350 also features Speedtech's exclusive AccuWeather.com®, patented Comfort Index™, which is the effect of temperature, relative humidity, wind speed and sun intensity on the human body. The formula can be adjusted based on sun intensity and is superior to Heat Index. The case is water resistant, shockproof, and the jackknife design allows for the most accurate measurements, as heat and moisture from your hand won't interfere with any sensors. The WM-350 can be tripod-mounted and accommodates the Model SM-WT wind tunnel accessory for very precise measurements. All WindMates meet NIST calibration standards and wind speed accuracy tested better than ±3%.
