UNI-T UT363 Handheld Anemometer Wind Speed Meter Wind Chill Air Temperature Gauge -14°F to 122°F (-10°C to 50°C) with LCD Backlit Max/Avg Data Hold

Perfect for what I needed

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.

The media could not be loaded. 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.

Rapido envioLo recomiendo!!

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!

No lo tomen personal, el producto funciona de maravilla, opero un dron y de manera instantánea me da una idea del estado del viento en tierra, sin embargo al no dejar extraer información de este dispositivo, no es posible hacer aplicación alguna ya sea laboral o académica por lo que es un bonito accesorio de lujo por ahora

Does what it suppose to

This has been great, more of a toy than being used in any PROFESSIONAL capacity and this works well enough. Found out that an industrial 140mm Noctua fan puts out 2x as much air as a 120mm fan, which was weird since wouldn't think that 20mm would make that much difference. Chalk it up to my ignorance on barometric. It was also great to see where I could use more air inside my case, which again, doesn't need blinding accuracy. Made even better by the compact size which means I could stick this between my giant tower cooler on my CPU and my back panel. Really the only complaint is that when you are using it in tight spaces like that, means you kind of have to blindly remember where the "hold" feature is so you can pull out the reader to check for the speeds. Which is necessary since I want to make sure enough air is going through the fins that my setup is working. I think the tiny 120mm fans spit out a speed of like 15MPH winds (they're industrial grade, not made for this purpose) So put the fan on the other side of the CPU tower with the passthrough fan and get a reading of about 15MPH, meaning zero speed loss. Thanks to it, getting silly low temperatures that most water cooling loops can't compete with. I'm hitting mid-50s on a 64 core CHIP, at 300W.As someone who wants to build their own PC for gaming, I recommend this tool, very useful.
