HoldPeak 866B Digital Anemometer Handheld Wind Speed Meter for Measuring Wind Speed, Temperature and Wind Chill with Backlight and Max/Min

Excellent product! Clear directions!

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.

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.

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.

I needed something to use to balance my HVAC system and picked this velocity meter. It worked fine. I just used an open topped cardboard box with a six inch circular hole to get a consistent reading of the velocity of the air leaving the HVAC registers in each room. This meter gave good, accurate velocities and permitted me to throttle the registers that were over supplying air to specific rooms. My only complaint is that the units font on the meter is a little small, but it was not really a concern.

Why did you pick this product vs others?:Very happy with it. Wish the screen would stay illuminated a little longer, but it does exactly what I wanted it to do.

Nice device, easy to use, high quality. Got mainly to use for HVAC use such as balancing the air flow from airconditioner and heater registers and checking temperature, dew point and humidity. Found that it also can be used to measure speed on a bicycle and walking pace if wind is not blowing!!! Living near sea level, have not had a chance to try it out on reading altitude.

The temperature reads way too high on this thing, more than the advertised error, and enough to not be reasonably functional as a weather tool. It is also really inconvenient to carry around. On top of that, it is easy for the on button to get bumped in storage, and have all the battery life go down the drain. I recommend that you don't waste your money here. If you do decide to try it anyways, remember where you kept your box, so you don't lose your refund ability...
