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.

Hard to get battery cover off. *by T***. on March 2, 2026* It does provide an air flow speed and rotates smoothly, so no reason to assume it wont work. Easy to set the desired units. If the need is to use this to get airflow, to then combine with cross-sectional area of pipe/vent to compute air flow rates, its probably good enough being an alleged 5% accurate. For sizing such flows its perfect. Not really for precise weather data capture. Getting the battery compartment open is a bit tricky, which is really the only ding I have against it. Removing the 2 screws is easy enough, but even with them out, getting the battery lid off is non-trivial as you have to lever it out from the screw hole areas, as the battery box lid has a box section that slides down into the body of the battery box space on the unit.. so its a bit friction fit there. Keeps the bulk of water out, but makes it hard to get apart to replace or remove batteries. A much smaller lip with an embedded silicone gasket to set against (held down by the screws) would have been a better design with only a $2 increased cost. ## Frequently Bought Together - BTMETER BT-100 Handheld Anemometer, Digital Wind Speed CFM Meter Gauge Air Flow Velocity Tester for HVAC Shooting Drone, Wind Chill, 14℉-113℉ Wind Temperature - Klein Tools IR1 Infrared Thermometer, Digital Laser Gun is Non-Contact Thermometer with a Temperature Range -4 to 752-Degree Fahrenheit - Klein Tools ET05 Digital Pocket Thermometer, HVAC Instant Read Thermometer with Backlit Display, Wide Measurement Range, Fahrenheit and Celsius --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/99166417-btmeter-bt-100-handheld-anemometer-digital-wind-speed-cfm-meter](https://www.desertcart.at/products/99166417-btmeter-bt-100-handheld-anemometer-digital-wind-speed-cfm-meter) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-22*
