HoldPeak 866B Digital Anemometer, Handheld Wind Speed CFM Meter

This is a straightforward handheld meter that has no downloadable memory however is good for field use for assessing real time wind speed. I have mine mounted on a tripod because it is kind of hard to hold it and move it around and things like that for giving period of time. Of course you have to know the wind direction if that’s what the purpose is I use it for measuring ground speed of wind for drone takeoff. The only thing that would compliment this would be a windsock. It has different units such as miles per hour. Kilometers per hour. Knots, meters per second, feet per minute. It also has minimum maximum and average. And the back screen is nice for the price of what limited use I have for it. It is a great anemometer. It uses two AA alkaline type batteries, which comes with it. The back cover is difficult to get off. Overall, I am happy with this purchase.

Works very well. The blades took a very small spot of superglue to get it perfectly balanced but still worked well before I did that. It's very sensitive but it doesn't have extremely fine resolution. I think it will do about .2MPH which is good enough for most purposes. Doesn't seem to draw a lot of vampire power so I don't feel like I have to take the batteries out every time I use it.

05.18.25 Works just fine, the big con is the battery cover. I played with it for about ten minutes and ended up using two tiny flat head screwdrivers simultaneously get it off. Sitting here typing, I think one or two O-ring hooks be useful. I am a little surprised that the cover did not break. Otherwise, it is as advertised.

Great anemometer. Used it to balance my HVAC in the house. Now it's a fun tool to measure airflow.

Works good

This is a nice and fairly well made Anemometer that I'm glad I purchased. It's easy to use, battery life is really good, accuracy seems good plus very sensitive for a value meter and the screen brightness is plenty for me to easily see the results. I can't really think of any complaints since it's lasted me a while now and has been used well more than a dozen times so far. I primarily use it to test various fans that I have. That way I can have a measurable output to log as data for comparison purposes. That way I will have a general idea of what I need for future fan purposes now that I have data to compare. There are several other air things that this can be used for, but that's what I'm using it for at this time. I want to use it for other purposes in the future and am excited to see how it will pan out. If anything changes for the good or negative, I will update my review accordingly. After many months, it has held up very well and is still going strong, so I'm not sure what to anticipate at this point. Time will tell.

You'd pay an arm and a leg for this at a chandler so I definitely have no complaint with this product. I can't say how accurate it is or isn't because I haven't tested it, but it works as advertised and I'm happy with the purchase. As long as I get a reading that is within a couple of units from true, then I've got enough data to work with. It is bulky (large) so it's a good thing it comes with a storage case because you certainly won't be carrying it on you regularly. The LCD is difficult to read if looked at straight on, but this instrument was designed to be held over one's head and in such a position, the LCD is very easy to read and the contrast is excellent. There's not much I can tell you about it, but if you're reading this, then you already know what it is so all I can really tell you is that I think it's easily worth the money. In the olden days when we didn't have Amazon or China we would have paid 3 times the money for the same handheld anemometer.

I like the simplicity and size of this handheld anemometer. It is easy to setup and use. It seems accurate although it’s hard to gauge without a standardized wind tunnel setup. The instructions and videos, typical of most Chinese made products, are considerably lacking and not well written. Specifically they do not explain the functions or how to use very well. But it was cheap and good enough for my use (measuring air speed coming from fans and HVAC ducts in my house). They should consider hiring a native English speaker to rewrite the manual and narrate the videos.

Bien et simple à utiliser. Dommage que la temporisation de l'eclairage de l'écran soit un peu trop courte. J'ai un doute sur la mesure de la valeur maximale qui ne correspond pas à la valeur max que je vois.

Good one

Je fais beaucoup de téléguidé, autos, avions et hélicoptères téléguidés et cet outil mest tres utile pour mesurer la vitesse de deplacement de l'air généré par les hélices d'avions et hélicoptères téléguidés au gaz, nitro et electriques. Je lai étalement essayer avec mon petit compresseur dair de faible debit a debit maximum du compresseur a 30cm de lhélice et ca ma donner la vitesse en temps réelle du déplacement de l'air. Equipé d'hélices sur roulements a billes et moteur sans brosse, cet anémomètre professionnel dispose de son hélice très sensible et ce meme a très faible vitesse de vent, loutil va retourner en temps réel ou en moyenne la vitesse de ce tres faible deplacement d'air. Je recommande pour ceux qui aurraient besoin de cet outil. Livrer dans les delai en 1 jour, cet article de 3dHero est a prix très abordable.

He usado este producto para calcular el aire extraído de una habitación por un tubo. He podido medir a qué velocidad circula (0,1 m/s) y esto nos permite calcular el caudal. Echo a faltar que no cambie el signo de la medición, cuando cambia el sentido del aire. Por lo demás es exactamente lo que buscaba.

This seems to do the job very well, when it arrived I was slightly surprised at the size as it looks fairly small in the pictures, it can be easily held in one hand however and the larger size blades means it will pick up even the smallest of breezes. It has a backlight function which illuminates the screen with a nice bright light, very easy to see in all lighting conditions. It also comes with 2 x AAA batteries which were hidden inside the battery compartment wrapped in plastic which I found to my surprise after buying a fresh pack of triple As and unscrewing the 2 small screws which hold the battery cover in place. The thermometer seems to be accurate, and although I do not own another anemometer I trust the readings which it is given as it seems really very sensitive to even the slightest shift in wind speed. Today it seems to be completely still outside my house, when I held this out of the window I was getting readings between 0.3 km/h and 0.7 km/h. Included in the box there is also a nice little zip wallet to keep it safe, a basic instruction booklet and a small black lanyard/wrist strap which screws into the threading on the bottom of the unit - this can also be mounted on a tripod using the same threaded hole. You are able to switch between m/s, km/h, ft/min, knots and mph as the unit of measurement, and celsius/fahrenheit for temperature. There is also a max/min function which could be useful if like me you are using this to judge whether or not it is safe to fly a drone. I am very happy with this purchase and would recommend to anyone.
