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 MeterMeasures 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 14F~140F, +/- 2.7 F display in 2 units CF(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 LoggingWith 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 Its 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 WONT change rapidly, theyll change slowly.

Great tool

First, the USB connection does NOT power the meter, so if you are going to do long term logging, your battery may die! WHY doesn't the USB power the meter???? What is so difficult to accomplish this? Second, from the videos I have seen and the one that I received, the fan is NOT balanced and has a heavy side. This would affect low air speed measurements! I screwed around with some weights to get the blade somewhat balanced but it is still a little off. Not worth returning because I would just get the same thing. Why is producing a balanced fan so hard???? Just shows how cheaply made this is! Also, does NOT do averaging... ONLY min/max/real time. Yet another lie in the description and functionality. Some buttons you hold for 3 second, some for 4... WHY??? Pretty poor and sloppy implementation to an otherwise fine instrument... guess you get what you paid for! A hint... check the fan's balance by holding the meter vertical, with no airflow, and see if the fan tries to swing to the heavy side. This will tell you that low speed measurements will probably be wrong.

Compared to my more expensive meters, this showed a fair degree of error. The velocity was much higher than my other expensive meters. And if the velocity is higher then it shows inaccurate cfms. Tried different setting but shows higher than what it's actually putting out

For some reason I forgot it was an anemometer and that the temperature readings and %RH would change instantly moving from outside to inside with no wind (air flow) outside or inside. I put it in my refrigerator, no air flow, so the temperature readings did not change rapidly, they changed slowly. The temperature sensors are inside the tunnels (or "holes") likely to shade them from radiation (like sunlight) to assure that the readings are for the air flowing through the tunnels. The instructions are helpful, making changes quite easy. And, the software/USB worked without any issues. Time now to get to tuning my HVAC system (air-to-air heat pump with three ducted air handlers for three separate zones). Not bad for tuning the home hot yoga studio either as to desired temp and %RH (as measured at output of a fan).

I wanted to make some psychrometric calculations but was sadly disappointed. Temperature was a few degrees in error but humidity was reading 17% when actual was 44-45%. I have some confidence in the numbers because I laid our three other devices, which were all of difference manufacture but all in agreement and impressively close. Perhaps they were rushing these BT units out the door and forgot to make the calibration. I had no standard for airspeed calibration to compare but after seeing these results I cannot trust any numbers that the BT66 reports.

Easy to use nice unit. Beware it comes with a 6” leash do not install it. When I was testing vacuum CFM the leash got sucked up into the process and broke most of the fan blades in the unit!!! My first time using it😂
