Color: BT-100APP Anemometer
First off, Amazon must have this unit stocked locally; it came in a single work day. Second, it comes completely as described: hand held/tri-pod mountable unit, 2xAA batteries, small driver tool for battery cover, attachable lanyard, USB cord (not sure why needed), manual, and carry case. the BT-100APP has instructions to UR scan with smartphone for app, or search your preferred play store for "intelligent anemometer"; once downloaded a refresh on your Bluetooth will pair and you're "almost" ready to measure your temp and wind speed.. the manual and box, and online does not mention that you might have to get into your phone settings; go to the wind app, and set the option to download/save your data prior to collecting it... other than that, the unit operates as described, and I even had another temp gauge, AND another wind device nearby, and it is even more accurate and sensitive. the temp is within 1/10th of an AcuRite weather station, and old school mercury gauge; the rotary vanes are more than traditional anemometers, and the low friction bearings are activated by lower wind speeds. I've left it out on a tri-pod overnight and the Bluetooth to the phone works thru windows/walls to 30plus feet. after powering down unit, data on phone can be saved as .xls (excel) or .txt (text) and either emailed, or downloaded to laptop or tower. I own more than four different type/brands of wind measuring devices (I use them to dictate where to install wind turbines on client's properties/buildings), and the BTMeter is by far the nicest, AND easiest to use, AND retrieve and save data; PLUS, one of the least expensive! great product. I will be buying more, and recommending to anyone needing to gauge air volume/speed. Hope this helps someone.

this weather station does what it’s supposed to do and is easy to use the best part about it is is that it recharges using a USB. In other words, you don’t have to put batteries in it. It’s easy to put on a tripod and leave it and you can monitor it with your phone. Don’t skip out on the case.

I bought this to use while sailing, both for wind speed and barometer readings for weather forecasting. It does both those tasks well enough. However, it comes with about the poorest user's manual I've ever seen. The one feature that most interests me is the ability to record barometer trends, but the manual only mentions it without explaining how it works. Useless! In the specifications section, there is a table of altitude vs. pressure, but without any indication of the units that are used. (They are meters and millibars.) It would also be nice to have some idea how long a set of batteries will last. The manufacturer should spend a few bucks and get someone who has something more than a Sesame Street grasp of the English language to write the manual. Aside from the documentation issue, I like the product and would recommend it. UPDATE: I ran some checks on this unit and found the following: The battery indicator is misleading. Using the supplied batteries (carbon-zinc, not alkaline - throw them away!), the battery indicator showed zero bars (discharged) after about 10 hours, but the unit continued to run (it does NOT shut itself off automatically) for nearly three more days. During that period, I periodically copied the stored barometer settings into an Excel spreadsheet and plotted the results. Contrary to what is said in the manual, the unit records the barometric pressure HOURLY as long as it is turned on, not every two hours as the manual states. The most recent reading is stored in register one, and earlier readings are shifted up one place when the new data point is stored. So, assuming the unit was powered on for the period of testing, the data in register 16 would be 16 hours old, and the data in register 5 would be five hours old. When I replaced the batteries, the stored data did not disappear, nor did the barometric calibration change. There is no obvious way to clear old data. When the unit is off, no changes to the stored data are made. When the batteries reach a certain discharge level, the backlight will no longer illuminate, and the screen will display "Er2" instead of the usual data. That's your cue to change batteries. When attempting to calibrate the barometer, the settings are made in millibars, not inches of mercury. So, if you know your local barometric pressure, you have to convert it to millibars to get the reading right. (1mb = 0.03"Hg, and 1013mb = 29.92"Hg) If you plan to use the instrument at sea level, and you are somewhere higher than sea level when you do your calibration, you can adjust your local barometer setting downward by 1mb or 0.03"Hg for each 30 feet above sea level your are at the moment. For example, my local barometer setting is 29.92 and I am 150 feet above sea level. I therefore set my barometer to 1008 mb (1013 - 150/30, or 29.92 - 0.15"Hg.) get 29.77"Hg at my elevation. If I then go down to sea level, the pressure will rise to agree with the local barometric pressure. The altitude readout on the instrument is effectively useless because there is no easy way to determine sea level pressure ahead of time, so the altitude reading won't be corrected for sea level pressure. The issued cited above would be problematic for a professional-grade instrument, but, for the price of this unit, you can easily ignore the problems and you can still get useful info. Enjoy!

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!
