BTMETERBT-100 Handheld Anemometer, Digital Wind Speed CFM Meter Gauge Air Flow Velocity Tester for HVAC Shooting Drone, Wind Chill, 14℉-113℉ Wind Temperature

I recently purchased the BTMETER BT-100 Handheld Anemometer, and I’m very impressed with its performance. This digital wind speed meter is perfect for measuring wind speed, air flow, and CFM, making it a versatile tool for both professionals and hobbyists.The device is compact and lightweight, making it easy to carry around and use on the go. The digital display is clear and easy to read, even in bright sunlight. I appreciate the straightforward button layout, which makes navigating the different modes simple, even for someone who's not particularly tech-savvy.One of the standout features is its accuracy. I’ve tested it in various conditions, and it consistently provides reliable readings. The built-in backlight is also a great addition for low-light situations.The BT-100 comes with a wrist strap and a protective pouch, which are nice touches that add to the overall convenience and durability of the product.Whether you're monitoring weather conditions for outdoor activities or checking airflow in HVAC systems, this anemometer gets the job done efficiently. Highly recommended for anyone needing a dependable and user-friendly wind speed meter!

Great price, works great. No complaints. Very simple to use.

Use it on my sailboat for backup wind readings and detecting airflow inside the cabin on hot days. The lighting is very useful for the nights where it's too dark to read. The display is good, and the battery life is phemonemal. It doesn't like speeds over 30kts of wind. Fits nicely in your hand and the attached lanyard helps a ton in windy precarious spots. Build quality is good, would love for it to be water resistant as measuring wind with rain still leaves something to be desired. In all a great product, and would buy again.

Quality. Works well. Easy to use

Purchased for a class I'm attending. In testing, it seems to work perfectly.

My HVAC system did not have dampers installed, I had hot/cold areas in the house and wanted more even temperature through my house, I installed the dampers and needed to balance the air flow this little manometer did just that. I was abe to balance the air flow through the dampers and get a much more even temperature throughout my house, very happy! Just wish my utility bills would drop by 30%-40%

Whatever your believe on climate trends, HVAC is increasingly important these days - and this inexpensive tool is what regular people like you and me need for PROVING what the airflow and temp is coming out of our vents when the HVAC techs (or property owners) say "it's working as designed."Use it to measure airflow somewhere you know the HVAC works well, and then compare those measures against your own system to see the deltas in CFM (Cubic Ft per Minute of airflow) which then arms you to press the HVAC firm or property owner into making your place comfortable.Helps to use a dB meter (even just a phone app) to measure acoustics of system on/off (to properly size the ducting), and an infrared/laser pyrometer for quicker temp measure of the vent surface (also super handy for measuring cooking surfaces, tire temps at the track...)The device is borderline 5 stars (I gave it benefit of the doubt) because its temp readout takes 3-4 minutes at a location to accurately read the temp vs. the laser pyrometer I pointed at the vent to get a baseline temp reading. Otherwise it's been a strong 5-star experience, seems like a quality design that should last a long time.

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.
