HVAC Anemometer CFM Air Flow Meter, Kethvoz Digital Wind Speed Tester 846A | Data Logging, 0.001 Resolution, Anemometro Measuring Airflow Velocity, Air Volume Temp, MAX MIN AVG, for AC Duct, Dryer Vent

KE-846A wind gauge is a pro HVAC anemometer based on detachable design, so you can read the wind measurement data easily when you put the vane sensor to measure wind speed overhead.CFM/CMM air volume reading would be displayed on the large LCD screen directly when you input the cross-sectional area value into the air flow meter. CFM (cubic feet per minute)= Duct cross-sectional area x airspeed ft/minProfessional HVAC tool wind tester to balance air flow output, air conditioning system, dust collection system and ventilation system etc.Specifications:Wind speed range: 0.3~45m/sTemperature units optional: ℃ / ℉600 groups wind measurement storage5 Wind speed units: m/s, km/h, ft/min, knots, mphWind temperature range: 14 °F -113 °F / -10 °C ~ 45 °CMore Features:Data FreezeAuto Power OffBacklit LCD ScreenMax / Min / AVG/ (2/3)MaxWind Temp Resolution 0.2℃Wind Speed Resolution 0.01m/sWind Accuracy ±3% of readingTemp Accuracy ± 1°F of readingPacking List1 x user manual1 x small screwdriver1 x 9V (6F22) battery1 x adjustable wind vane sensor1 x KE-846A Pro CFM anemometer1 x Portable ABS wind gauge case
