UNI-TDigital 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

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.

The unit works and it’s a good price, but it does not pick up low speed airflow. Not as good as more expensive units made by kestrel.

This anemometer/thermometer appears to give good readings, to the extent I can test it. It's easy to hold and easy to read. I wish the selected units didn't reset every time I turn it off. If you want MPH and Fahrenheit it'll take four short clicks and one long one on the units button to get there, every time you turn it on. And I wish there was a case or some protective covering.My tests include the following:--*- Measure the outside temp, along side a trusted thermometer: 85.2 vs 84. I may not have let the trusted thermometer settle long enough. See first pic.--*- Measure the inside temp beside the same trusted thermometer: 72.6 vs 73. Note the trusted thermometer doesn't read in tenths. See second pic.--*- Take it down to my dock where the winds were light but of steady direction. I took a short video showing my windsock in the background and this device in the foreground. Notice when the windsock indicated the wind picked up, the anemometer reading increased as well. It's also good the anemometer can read such low wind speeds. Its sensor (fan blades) is quite sensitive. Based on my long time reading of wind on the water (as a long time sailor) I find the anemometer to be a good indicator of low wind speeds.--*- Blow a keyboard cleaner (wind generator) into the sensor from about six inches away. The cleaner puts out a good burst, with three settable velocities. I have no idea what the wind speeds are for it. In the last three images I uploaded (not allowed to upload second video) you can see, on average, the anemometer showing increasing speeds as I step the cleaner up through its three settings. I can believe it's pushing more than 40 MPH of air at the end.So, I find this anemometer acceptable for my uses (mostly sailing and flying a drone). It beats the old tube with a ball in it I used decades ago (and you can still buy here on Amazon for about $70).One star off for not retaining setting, and no case/cover. The device itself seems fine.

Like many avid golfers I am always looking for some reason why I can't shoot in the 70's. I have successfully been able to eliminate lack of skill and ability as root causes and am now focused on environmental factors due largely to climate change. The droughts in California where I mostly play have ravaged the golf courses causing poor fairway and green conditions due to lack of irrigation but the biggest factor I have discovered is the incessant climate change inspired wind which blows my shots all over the golf course resulting in my inability to achieve my deserved lower scores. I saw this handheld anemometer on Amazon and realized that if I could accurately know the wind speed I would be able to adjust my club selection and swing to provide the shot results I am seeking. The UNI-T UT363 BT has everything I need to master the bothersome wind effects and lower my scores to where they belong. The unit is a small hand held tool which is well constructed and nicely engineered to provide instant temperature and wind velocity as well as minimum and maximum speeds in the units of your choice (meters per second, km per hour, feet per minute, knots, and miles per hour with temperatures available in C or F scale). The unit has Bluetooth capability but I needed to download the free iENV application from the iTunes App store to make it connect. It connects easily with my iPhone and has a host of features available on the app. I would caution the engineering community to actually read the instructions which are included with the unit to eliminate undue frustration while trying to set the unit up and getting the Bluetooth connected - no app no joy in my case initially. I have played outside the house with it and find it to be easy to use and I am impressed with instant response to wind velocity changes and I believe that the AVG setting will prove most useful on the golf course in shaping my game to meet the challenges of climate change induced wind. The unit measures up to 67 mph on wind velocity and 122 F on temperature, either of which would be cause to immediately proceed to the 19th Hole to have some well deserved liquid refreshment. I have yet to take it out on the course to test my hypothesis of game improvement but I am confident that I will know the wind speeds whether on the golf course or boating on the lakes. I like the simplicity of the unit, the performance demonstrated and size that will fit nicely in my golf bag along with my many other game improvement devices. My only reservation is that the instructions indicate the unit is for "indoor use" which would limit it to measuring HVAC or fan speeds which I believe is probably an error on the part of the manufacturer. I like the unit and would buy it again if it proves to lower my golf scores and/or breaks due to misuse on my part.

I was interested in one of these anemometers so I could see if my fans, installed on my 3D printers. were pushing enough air when the fan was engaged to cool the hotend. I should have researched better because this model does measure airflow but it doesn't measure wind speed in CFM which was what I need, so totally my bad. So i had to improvise and use the ft/min measurement to see what a new fan was recording. I did have the manufacturer's CFM spec for the new fan so I was able to crudely use that as a baseline and then measure the airflow ft/min on the installed fan and compare the 2 measurements.I know.. it's not the most elaborate and accurate way to measure how much air being pushed but I'm not trying to win a Nobel prize. I just wanted to see if the current fan was pushing more or less air than a few new fans that I purchased. It worked for what I needed it for, I just wish it had the wind speed in CFM measurement but provided this is a basic unit you can't have too much an entry level unitI did try pairing it with the app using bluetooth and had no issues. it pretty much just allows you to see the readings from the unit if it's placed in a location where you can't easily read the screen. There is a threaded insert on the back of the unit if you need to attach it to a tripod or pole. Although I would have thought the insert would have been placed better position, like at the bottom of the unit, but I guess there was a better reason to place it towards the neck of the unit. There is a backlight option if you need to see the screen in the dark.
