Digital Anemometer UT363BT Handheld Wind Speed Meter Wind Chill Air Temperature Gauge -14° ~122°F /-10°C~50°C for HVAC Shooting Drone with LCD Backlit Max/Avg Data Hold

Pleased with the purchase, works well for the intended purpose. As others have stated, it would be better if it retained your settings, e.g. MPH when powering back up.

This UNI-T UT363BT is my first anemometer and it's pretty fun. I've got some other UNI-T meters so knew their quality. I've used it to measure fans, comparing airflow on different speeds, and to measure the spread (traditional versus tower fans). I've also used it to measure PC case fans. I was hoping to be able to measure slight air currents in the room but it's not sensitive enough for that. The app is great for sticking the meter inside some small space and still being able to see the measurement. It eliminates the need for a propeller on a wire, which would make the unit more delicate. The app is pretty clunky and if you've changed the overall font size on your phone, the temperature pushes off the bottom of the screen. The app does improve things somewhat in that it shows two decimals for the wind speed, and gives quick access to the max, avg, and hold buttons. Logging works and can be exported to an excel spreadsheet file for easier analysis and manipulation. It can't measure low wind speed, despite product specifications saying 0-30m/s. I can have a breeze barely spinning the propeller for tens of seconds but get 0.0 on screen. Then as as I gently increase air speed it jumps to 0.4, oscillating between 0.0 and 0.4, then jumps to 0.8, then the next jump is 1.0 (1.05 in the app). The resolution is listed as 0.1m/s but it's really 0.4 at the low end. Part of the limitation is the small propeller, but even when it picks up some rotation the meter can show 0.0 so it's also a processing issue. I'm thinking that for light breeze a DIY ribbon hanging will be far more sensitive than any propeller-based unit can be. The reading jumps around a lot, but the averaging feature greatly improves the stability (and increases precision in the app since it shows two decimal places). The hold feature is useful when measuring where you can't see the screen but don't have it connected via the app. Near some electric motors it gives false readings up to 4.3m/s when the propeller isn't spinning. With one small air purifier it does this over two feet away from the unit! I wonder why they don't use an optical mechanism to detect the spinning propeller.

I don’t use it daily so I didn’t need an expensive one but so far this thing has been right on the money and easy to use!

Buen producto precio calidad

Perfect for what I needed

It gives rough speeds but the fan is so unbalanced I wouldn't trust the reading with anything important.

Works great for what I need which is basic information. Very pleased for the price!
