• 6-in-1 Weather Meter: With this pro wind speed meter you can get environmental conditions in seconds in the palm of your hand including Wind Speed, Temperature, Humidity, Dew Point, Altitude, Barometric Pressure, Wind Chill. A must-have tool for any outdoor activity Professional & Multifunctional: This digital handheld anemometer has functions such as: unit switching of wind speed(m/s, km/h, ft/min, knots, mph), wind temp(℃,℉), Altitude(M, Ft) and bar pressure(inHg, hpa), Max/Min/Average Wind Speed, battery level display, auto off, backlight, etc Barometric Data Logging & Altitude Correction: This weather meter can record 16 sets of barometric pressure data. Since altitude is calculated from barometric pressure, you can also manually correct the barometric pressure before measuring the altitude to get more accurate data With Tripod Hole & Hand Strap: This hand held anemometer has a tripod hole that allows you to free your hands while measuring. It also comes with a hand strap, which prevents it from being dropped or lost. This ensures every shooting, sailing, or drone flying safer and more enjoyable Wide Applications: This handheld wind meter is ideal for outdoor activities like surfing, drone flying, kite flying, boating, golf, etc. And it is sensitive to measure very low air flow in HVAC installation, duct vent. Which can be a good helper in CFM calculation. You can simply calculate the CFM: Air Flow in CFM =Wind speed x Duct Cross Sectional Area
