## Description

BTMETER BT-866A Pro Handheld HVAC Anemometer for CFM Air Flow, Wind Speed Meter Gauge Measures Wind Velocity Temp%RH Dew Point with USB Sync to PC

## Features

- ★【Wind Data Sync on Computer】 This wind velocity meter can measure Wind Speed, wind temperature, wind flow, relative humidity(%RH) and dew point, provides Max / Min of wind velocity reading to balancing the HVAC system. Built with sensitive 8 vanes to pick up slow winds down to 0.01 resolution. Comes with a USB cable and PC software for wind data logging, analysis and monitoring.
- ★【High Accurate HVAC CFM Meter】Measures high Wind Velocity range 0.3~40 m/s, +/- 2.0% + 50, display in 6 units: m/s, km/h, ft/min, knots, mph, fpm; Wind Temp Range 14°F～140°F, +/- 2.7 °F display in 2 units ℃℉(Celsius,Fahrenheit); Air flow vlume range 0~999900 ft3/min. 💖Smart anemometer display air flow velocity and CFM reading directly, no more manual calculation💖
- ★【USB Data Logging】With a metal screw hole in the bottom so you can mount it on a tripod for hands-free operation. Support to connect the wind meter to computer via USB port, for monitor and record wind speeds, temperature, CFM air flow and RH, perfect for balancing air flow in HVAC tasks such as: duct vents, AC air output testing
- ★【Portable Anemometer】 It’s a handheld pocket size wind speed indicator comes with protective case, Large Backlit screen, Low battery indicator and auto shut down to save the battery. Portable for indoor and outdoor wind measurements,such as: Long range shooting,Boat Sailing, Kite flying, Climbing, Drone driving,Vent, turbine air flow testing etc.
- ★【Tips for Wind Temp %RH Testing 】 The temperature sensors are inside the left and right holes, to shade them from sunlight to assure the wind reading are for the air flowing through the holes. So without air flow, the temp and %RH reading WON’T change rapidly, they’ll change slowly.
