Portable WindMate wind meters have been reviewed by experts in the field and have won various industry awards. Each unit is only 5.5 inches long when closed, and weighs just over 3 ounces - perfect for taking to the field, or adding to that already-stuffed range bag. The unique, jackknife-style case allows more precise wind speed readings than other meters, because your hand is distant from the wind impeller, allowing undisturbed air flow measurement. It then folds to protect the unit when not in use. WindMate meters come with a wind vane to ensure accurate measurement on the wind axis. All units can be tripod mounted and will accommodate the Model SM-WT wind tunnel accessory for more precise readings as a stationary sensor or for long-range shooting. The 200, 300, and 350 models feature a digital, USA-made fluxgate compass which allows wind direction, cross/head/tail wind calculations, and more, all on an easy-to-read LCD display. All WM-series meters use the readily available, CR-2032 lithium battery, included with each meter, which provides approximately 400-hours of operation. WindMate wind meters meet NIST calibration standards, are wind speed accuracy tested to better than +/- 3%, and have a 2-year warranty.
The WindMate WM-300 measures wind speed and direction, temperature and humidity. Its Swiss-made, self-calibrating humidity sensor helps maximize use in the field. In addition to relative humidity, the unit measures dew point, wet bulb, Delta T, air temperature and computes wind chill. It also includes Accuweather.com's patented Comfort Index, which is the effect of temp, wind speed, relative humidity and sun intensity on the human body and is superior to Heat Index. Unlike traditional compasses, the USA-made fluxgate compass in the WM-300 reads when held vertically and can be used for taking bearings. These features make the WM-300 the perfect tool for professionals, hobbyists and recreational users.
