XinJiaYi Digital Anemometer Portable Air Flow Meter CFM Meter for HVAC Fan/Shooting/Drone Wind Gauge with Wind Temperature/Humidity Sensor Black

• Improved anemometer: The grey anemometer not only measures air velocity/wind speed, air volume, but also relative humidity, temperature, dew point and wet bulb temperature. Built-in high-precision sensor and sensitivity fan, so you get a more accurate measurement. The digital wind speed meter is perfect for weather station, HVAC system testing, shooting, boat sailing, surfing, hiking and other outdoor activities.
• Backlight and automatic/manual shutdown: press any button to activate the backlight of the wind gauge for 12 seconds, convenient to read in a dark place, press "Mode" + "SET" at the same time to turn off the wind gauge, or no operation for 14 minutes, it turns off automatically.
• High accuracy: range of wind speed meter: 0.3 ~ 40 m/s; temperature range: 14 ~ 140 °F; accuracy of temperature: ±1 °C; accuracy of wind speed: ± (2% rdg + 50 dgts). CFM meter: 0 to 99990 0 to 9.999 ft2; CMM: 0 to 99990 0 to 9.999 ft2; CMS: 0 to 9999 0 - 9.999 m2.
• Easy to use: measures different readings such as Max, Min, Average, current wind speed. The user interface is intuitive, measures wind speed in 6 units: m/s, km/h, mi/h, ft/m, ft/s, knots and automatically calculates CFM. The Beaufort wind scale rating is clear for you to know the current wind scale level.
• About us: 2 x 1.5 V AAA batteries included so you can get started when you receive the wind tester. If you have any problems or suggestions about our stud finder, please let us know and we offer 7 x 24 hours technical support and customer service.
