The WM-300 is a comprehensive instrument for agriculture, forestry, emergency management and other industry professionals. The Swiss-made humidity sensor is lifetime calibrated! In addition to relative humidity, the unit measures dew point, wet bulb, Delta T, temperature & wind chill. Like the WM-200, it uses a wind vane & a USA-made fluxgate compass for digital wind direction, which also calculates crosswind & head/tail wind readings. Unlike traditional compasses, the WM-300 reads when held vertically and can be used for taking bearings. It also includes our Accuweather.com patented Comfort Index, which is the effect of temp, wind speed, relative humidity & sun intensity on the human body and is superior to Heat Index.
WM-300 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%. 2-Year Warranty.
