HP-866B-APP Digital Anemometer,Handheld APP Data Support Wind Speed Meter
- Free Shipping
Works well. Large easy to read and setup. Not sure about accuracy since I was not able to verify with a more accurate instrument. A bit bulky though. Not very pocketable. Not sure about durability. Plastic body. Will give a better rating once I've checked within a few weeks.
I did not rate the accuracy of this device because I have no benchmark to compare (who does?).
I live in an apartment complex that is nestled in a veritable wind vortex. Within this vortex, the independent variables are the open doors/windows combinations which can regulate the fluid velocity of the rate of atmosphere whipping through my apartment.
Basis: on any given day, the wind is bustling at 20 mph at the southern edge of my balcony, according to the device. This is the dependent variable average. I can manipulate the various sliding door and/or windows to control the velocity around a cooling and pleasant 10 mph breeze throughout.
There are, of course, the hockey-stick spikes. This device is rated to measure up to 30 mph. I had the fortunate timing, and measured a gust rip through this place at 30.4 mph. Yes, pictures flew off the walls, towels torn from their racks, and even the TP spun off its roll. I turned off the device immediately, because of concern of exceeding the manufacturer's stated limits, yet wondered if it was a true limit since it was (briefly) surpassed?
I marked the "Easy to Read" evaluation in the middle. The device does have a backlight, which is not useful diurnally. In the daytime, the glare on the screen can be a challenge. This is mostly because of the subtle angular shifts necessary to read the display, which can also affect the air flow through the device. The only work-around for that, I imagine, would be an option to change the contrast in the display?
Bottom line, it measures well enough for my immediate and non-scientific needs, and I need to move out of this crazy cyclone of an apartment if I want to keep my towels!
First off, 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 HP-866B-APP 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 HoldPeak 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.
I received this sin time to take it out to the lake for our clubs PHRF series. This was spot on accurate and helped us find and stay in the wind on a day that the wind was spotty at best. When checked with another brand anemometer it was spot one and responded quicker. This is by far a great addition to my sailing gear. It also works great at the rifle range when the wind is blowing. Can definitely help with determining windage. It is easy to read and has a tripod socket on the bottom so you can set it out aways and see what the wind is doing down range. I highly recommend this!
Ok so firstly, I bought this because I run a Youtube channel about cars, motorcycles, and technology and I like to do reviews that are fact-based with actual test results.
For example, I am using this anemometer to review a motorcycle windscreen (to measure wind force before and after the windscreen on various parts of the human body). The HP Meter anemometer was perfect for the following reasons:
1. High accuracy.
2. Clear digital display so my camera can easily see the results before and after the windscreen.
3. Nice high quality back light with auto deactivation to save batteries if you leave it on by accident.
4. It has a mounting port that works with tripods, etc. on the bottom (this was essential for me because I had to connect it to my motorcycle).
5. Portable and light weight, yet has a solid build quality.
I also plan on using this for other reviews (aerodynamics on cars, etc.). Great product at a great price that every car guy/gal/DIY'er should own!!
Given their quality, I also bought a laser thermometer from them, which I also recommend.
PS - I will upload my windscreen review here in the coming days.
Wanted a simple cheap anemometer to assess wind speed and max gusts for preflight of our drone. I've now used this meter for two weeks. The HP-866B satisfies our wind measurement requirement and has the added feature of temperature both F and C. I like having the low battery indicator, simple (but cheap) carrying case, as well as the back light. The elegant simplicity, measured accuracy, extremely low price point (~$23), and ease of use were my key evaluation criteria for the '5' scoring.
This is a great unit. It almost deserves 5 stars. Before I bought the HoldPeak, I purchased an Ori-Glam. The Ori-Glam was a disappointment because the vane did not work. This HoldPeak has an excellent vane on it that is well-protector from damage.
This is one of those neat things to have around. I originally bought this to measure the air speed coming out of the heating vents. It helped quantify how the sharp bend in the air duct was restricting the air flow. After the installer corrected that, I used it in setting the vents so the whole house heated evenly. It works perfectly and have not had any issues. Accurate. Fast delivery and comes with a zippered, padded case.
This is a great unit for the price! Not flimsy, and it seems pretty accurate. I drove around in my car at different speeds and this device was within 1 or 2 mph of the speedo, which is plenty good enough for my needs. And the case is better than I thought it was, instead of just flimsy material, it is somewhat sturdy, enough to hold it's shape when empty, and it provides some padding.
