You just need to aim at the target to measure the current temperature rapid and safe without the need for surface contactï ã€Wide Application Anemometer: ã€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. Its sensitivity makes it a valuable tool for CFM (Cubic Feet per Minute) calculations, simplifying the process with the formula: Airflow (CFM) = Wind Speed x Duct Cross-Sectional Area; Product DescriptionH HOLDPEAK Handheld Anemometer, Digital Wind Speed Meter for Air Velocity, Digital Laser Infrared Thermometer -50 to 550â with Adjustable Emissivity, Max/Min/Average Wind Speed for Drone Flying Kite
