ET-977 Measurable Wind Chill Airflow Velocity Industrial Weather Station HVAC Sailing Flying Hot Wire Anemometer Wind Speed Meter

1.General Description This hot wire thermo-anemometer is ideal for low air velocity and volume measurement. The slim plug in telescopic hot wire probe extends from 0.26 to 1.2m (inc handle) has a probe sensor head 8.5mmØ and is ideal for grille hoods and diffusers. It is excellent for ventilation surveys, air conditioning, clean rooms, flow hoods, air balancing and environmental monitoring. 2.Accessories ◆User’s manual ◆One type-C cable Range Resolution Accuracy Air velocity 0.1～25 m/s 0.1 ±(5%+1d) 0.3～90.0 km/h 0.1 20～4925 ft/min 1 0.2～48.5 knots 0.1 0.2～55.8 MPH 0.1 130～7500 CMM 1 157～39370 CFM 1 Area set 0.1～9999 CM²/0.1～9999㎡/0.1～9999ft² Sampling time 2 time/second Air velocity level indication Digits display 3-color LED light alarm Audible alarm(can be disabled) Alarm for 20 seconds,stop for 1 minute, and then cycle the alarm.
