  • Accurate, easy to use, and perfect for outdoor activities!
Color: BT-100 Anemometer
I picked up this BTMETER anemometer to check wind conditions for some outdoor hobbies, and it has been a fantastic addition to my gear. It’s compact, reliable, and provides a lot of data for such a portable device. • Highly Accurate: I’ve compared the readings to local weather stations, and it’s consistently spot on. It picks up even the slightest breeze, which is great for precision. • Feature-Rich Display: The backlit LCD is very easy to read, even in direct sunlight or at dusk. I love that it shows wind speed, temperature, and wind chill all on one screen. • Versatile Measurements: Being able to switch between units (like mph, knots, or m/s) is super helpful depending on what I’m doing. • Solid Build: It feels durable enough to toss in a bag without worrying about it breaking. The fan spins freely and the response time is almost instant. Whether you're into sailing, flying drones, or just need to check HVAC airflow, this tool is excellent. It’s a great value for the price and much more professional than I expected! ... show more

  • Love this device.......Butt....
Color: BT-100 Anemometer
I received the unit today and was excited to try it out. The unit does a great job measuring air speed. I will use this to adjust the AC /Heat vents in my house. The downside is the thermometer does not measure temperature accurately. I compared the unit temperature read out to an accurate temperature reading thermometer and the readings were about 10 - 15 degrees apart. I am disappointed in that. I gave the unit plenty of time to stabilize by laying it across the AC vent. ... show more

  • Large Diameter
Color: BT-100 Anemometer
Love the sizing on this meter. Good to capture the full diameter of flow, not only one side or just the center, but a full flow especially from a pipe. Reads well, easy to use, and fits nice in the hand. Good meter and buy overall.

  • very nice handheld anemometer
Color: BT-100 Anemometer
I have a need to be able to measure the flow of air and was looking for a low cost solution that I could get fast. When I saw the BTMETER BT-100 handheld anemometer I decided to give it a try. One review I read while deciding which product to buy concerned difficulty in removing the battery door. The battery door is actually very easy to remove if you know how. To remove this door you first need to remove the two screws with the provided screwdriver. You then need to pull the door EXACTLY straight out. The fit is tight so if you lift one side more than the other it will make it much harder to pull out. With the two screws out I was able to put a fingernail under each side on the part that holds the screws and pry up. If you do this or something similar it is very easy to remove. The instructions for this meter are very minimal so my next couple of comments relate to use of the instrument. The device measures temperature and the spec is +/- 3.6F. A lot of the reviews complain that the temperature measurement doesn't work. I put it in a room that is approximately 71F. The temperature on the meter was 69.9F which is within the tolerance. The important thing to understand is that it is very slow to change. It took around 30 minutes to get up to that temperature (I didn't measure it initially because I didn't know it was so slow). I am not sure why it is so slow but if this is important to you than FYI. There is a button on the meter so you can display temperature in F or C. The main reason I got the meter was to be able to measure the flow of air. The fan blades are very sensitive to air flow. Just picking up the meter causes the fans blades to turn. I don't know about the accuracy of measurement for air flow. For my usage it is more important to get a number then I want to know the amount of change when I change things and for this usage the meter works great for me. The only problem I had was I sometimes put the meter in a spot where I could not see the display. I finally figured out how to work around this problem. There is a button labeled MAX/MIN. Pushing this button toggles it between MAX, MIN and nothing. If it is in MAX mode it will continue to display the maximum value when you remove the meter from the air flow. I started to use the meter in MAX mode in the cases where I could not see the display. The main cause of this problem was the minimal instructions that the meter has. There is a timeout (to save on battery drain) where the meter turns off and it is approximately 15 minutes. When it turns back on again the units I selected for air speed and temperature were preserved. The MAX/MIN setting was not. This is a quick review that I will update after I have used it for a longer period of time if there is something else of interest to add. At this point in time I am very happy with this meter. I got it overnight free with Amazon Prime! ... show more

  • Handy for drone users
Color: BT-100 Anemometer
I'm happy with this product. For the price, it is well built and works fine in all regards. I use it for checking the wind speed around me when flying my drone. My mini 5 pro has a wind speed "limit" of 27mph. What this anemometer does for me is, after using it for a while, it's helped me remember what a given wind speed feels like without looking at it. So I just take into account that wind speed at altitude will always be more and take it from there. The device works great and seems very accurate and very sensitive. Just a note. I would like to praise the seller for their customer service. Although it says final sale and no returns, mine arrived and would not power up. I sent them an email with a short video showing them that even with new batteries, it won't power up. They were extremely nice and immediately sent me a replacement without me having to return the old one. Now that's customer service! I also like that you can mount this on a tripod. I use it all the time. ... show more

  • Nice affordable unit
Color: BT-100 Anemometer
We use these to test the CFM on our kilns and air dry yards for a lumber company. They work very well. They’re not terribly priced. They seem to be quite accurate compared to some of our very expensive ones within a percent which for the price is pretty good. I’ve never had a battery failure in a few years that we’ve been running them overall they were very well and it’s easy to use. ... show more
