Review: very nice handheld 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 desertcart Prime!
Review: All products should be this easy to use - After installing the batteries (a small screwdriver was included as a thoughtful accessory) it took less time to begin using this device than it took you to read this sentence. Press the "on" button and it begins reading instantly. The buttons are intuitive. Press "max/min" once and you'll get the maximum wind speed. Press it again to get minimum wind speed. Press it again to go back to normal mode. Similarly, "Avg" gives you average speed over time. Really like that this comes with a protective case. The backlight is very bright - even in daylight it makes reading so much easier. It's also a must-have at night (for those like me who may use it in darkness for measuring potential windchill). Backlight turns off automatically after 15 seconds (presumably to save battery life). I tried to see if this has auto-off feature but after leaving it on for several minutes it doesn't turn off. This can be a good thing when measuring min/max/avg wind speed though. Booklet that comes with this device states ±5% accuracy, and it's rated to 65mph (plenty fast wind speed for almost all occasions). These are decent accuracy and speed ratings for this great price range. Because this is a "directional dependent" device, I recommend using a wind sock or similar method of knowing wind direction. Aligning this device with the wind direction gives best results.

### ⭐⭐⭐⭐ Simple and accurate airflow meter
*by B***B on March 31, 2026*

I’ve been using the BTMETER BT-100 anemometer mainly for checking airflow at vents and returns, and it’s been a useful little tool. It measures wind speed, temperature, and airflow (CFM), which makes it handy for basic HVAC diagnostics. The readings update quickly and seem consistent, and the backlit screen makes it easy to read in darker areas like attics or utility rooms. It’s lightweight and easy to carry around when moving between vents. It’s not a high-end professional meter, but for the price it does what you need. The only downside is the plastic build feels a bit basic, so I wouldn’t be too rough with it.
