【Multifunctional Digital Anemometer】Neoteck Wind Gauge goes beyond measuring wind speed, air volume, wind power level, temperature and humidity. It also records maximum and minimum values. Ideal for various outdoor activities like long-distance shooting, mountaineering, sailing, kite flying, drone piloting, and CFM air flow testing. You can benefit from comprehensive meteorological data for informed decision-making and enhanced safety during outdoor pursuits 【Precision Measurement 】With a sampling rate of every 5 seconds, Neoteck wind speed meter offers a wide measurement range from 0.895 to 67.11 mph (0.4-30mm/s) with an accuracy of +/- 2% and a resolution of 0.1m/s. You can enjoy accurate wind speed data for diverse applications, ensuring precise decision-making in any scenario 【Multiple Unit Options 】Featuring 6 wind speed units (Knots, km/h, mph, m/s, ft/s, ft/min), 3 air volume units (CMM, CFM, CMS), and 2 cross-sectional area units (㎡, ft²), air flow meter provides flexibility and convenience. You can easily switch between units based on preferences and regional standards, enhancing your experience and adaptability 【Temperature and Humidity Testing】Equipped with temperature and humidity testing capabilities,handheld anemometer offers accurate readings with a relative humidity measurement range of 0.0% to 99.9% RH and a temperature range of -20.0℃ to 60.0℃ with an accuracy of +/- 2℃. NOTE:Temperature and humidity sensor may take at least 30 minutes to adapt to a new environment 【Humanized Design】Featuring a backlight, data hold and auto-shutdown functions, this CFM meter ensures you convenience and energy efficiency. The auto-shutdown feature, which can be disabled, hold “HOLD” button and press power button for 2+ second to turn on. 5 beeps mean auto shutdown off Technical Specifications:
