Features 5
- MEASURE LIGHT AIRFLOW WITH CONFIDENCE: This digital anemometer measures 0.6767.1 mph with 5% accuracy and air temperature from 14113F (-1045C); its sensitive eight-blade impeller responds to light airflow at HVAC vents and outdoor sites.
- CHECK HVAC AIRFLOW AND CALCULATE CFM: Compare air velocity at supply vents, return grilles and exhaust fans to spot differences in airflow. Use the readings with the vent area to help calculate CFM and investigate uneven ventilation around your home.
- TRACK GUSTS, LULLS AND AVERAGE WIND: MAX, MIN and AVG readings help you see how wind changes before a drone flight or while sailing. Choose mph, m/s, km/h, ft/min or knots; F/C air temperature and wind chill readings add context to outdoor checks.
- BACKLIT DISPLAY AND SECURE GRIP: Read your handheld wind speed meter in dim equipment rooms or after sunset. Non-slip side grips and an included wrist strap help keep it secure; the backlight turns off after 15 seconds to conserve battery power.
- TRIPOD MOUNT FOR HANDS-FREE CHECKS: Attach your wind gauge to a compatible 1/4-inch tripod for extended measurements at the job site or outdoors. The included carrying case keeps your kit together between uses. Tripod not included.
Description
Weighing just 5.4 oz and measuring 6.5 × 3.4 × 1.5 inches, this handheld anemometer fits easily in your tool bag or backpack. From HVAC airflow checks to drone flying, sailing, and target shooting, keep wind speed and air temperature readings close at hand—wherever the day takes you. What wind speeds and temperatures can it measure? This digital wind meter measures 0.67–67.1 mph with ±5% wind speed accuracy, plus air temperature from 14°F to 113°F. Choose from five wind speed units and switch between °F and °C. Can I use this anemometer to check HVAC airflow? Yes. The HP-866B measures air velocity at HVAC vents, duct openings, and exhaust fans, helping you compare airflow between outlets and check home ventilation. Does this airflow meter display CFM directly? No. CFM depends on both air velocity and the opening’s area. Simply multiply the average air velocity measured by the meter (ft/min) by the opening area (ft²) to calculate CFM. Is the screen easy to read and the meter simple to use? Yes. Clearly labeled buttons make it easy to switch units and view MAX, MIN, or AVG readings. The backlit LCD shows wind speed and air temperature together, including in low light. Can I mount this wind meter on a tripod? Yes. The HP-866B has a standard 1/4-inch threaded mount for tripod use, keeping your hands free for target shooting, drone flying, sailing, or extended HVAC airflow checks. Tripod not included.

Good inexpensive anemometer.
Color: 1Pcs 866B Anemometer
This is a straightforward handheld meter that has no downloadable memory however is good for field use for assessing real time wind speed. I have mine mounted on a tripod because it is kind of hard to hold it and move it around and things like that for giving period of time. Of course you have to know the wind direction if that’s what the purpose is I use it for measuring ground speed of wind for drone takeoff. The only thing that would compliment this would be a windsock. It has different units such as miles per hour. Kilometers per hour. Knots, meters per second, feet per minute. It also has minimum maximum and average. And the back screen is nice for the price of what limited use I have for it. It is a great anemometer. It uses two AA alkaline type batteries, which comes with it. The back cover is difficult to get off. Overall, I am happy with this purchase.

Works well
Color: 1Pcs 866B Anemometer
Works very well. The blades took a very small spot of superglue to get it perfectly balanced but still worked well before I did that. It's very sensitive but it doesn't have extremely fine resolution. I think it will do about .2MPH which is good enough for most purposes. Doesn't seem to draw a lot of vampire power so I don't feel like I have to take the batteries out every time I use it.

Inexpensive but Accurate
Color: 1Pcs 866B Anemometer
After both my wireless Acurite and LaCrosse anemometers failed, I decided to buy the HoldPeak 866B hand-held unit to calibrate a hard-wired anemometer I am building using an Arduino Mega connected to the mechanical parts of my defunct Acurite. The box containing the HoldPeak had one corner that was crushed. Fortunately, the unit itself, which was in a sealed plastic bag, was undamaged. The attached photos show all that was included - the unit, the zippered carrying case, the lanyard that screws into the tripod mounting hole, and the instruction sheet. Of course the unit would not power up right out of the box because the two included AAA batteries were wrapped in plastic. I used a jeweler's Phillips screwdriver to remove the two small screws holding the battery compartment cover. The cover itself required a knife blade to pry it out. Removed and unwrapped the batteries then reinstalled them. The unit now powered up. I found the included, bare-bones instructions somewhat ambiguous regarding the use of the MAX/MIN and AVG (average) buttons, I had assumed, based on the skimpy instructions, that after you completed a measurement, you could switch between MAX and MIN and see those two wind speeds displayed. Finally figured out that is not how they work. What the instructions don't say is to get the MAX wind speed, you first must press the MAX/MIN button so that MAX appears on the display. Then do your measurement. When you are finished, the display will show the maximum speed and hold it until you either turn the unit off, hit the MAX/MIN or AVG buttons, or take another measurement where the wind speed exceeds that shown on the display from the first measurement. I like this feature. You can take a reading without the MAX icon showing and, after you finish, hit the MAX button but the reading will not be the max speed that occurred but some lesser speed, Why the MIN (minimum) wind speed feature was included is beyond me. Because, let's face it, every measurement you make is going to have a zero minimum. And that is exactly what is shown (0.0) every time you begin a reading with the MIN icon showing on the display. Use of the AVG feature is also rather hokey. Before you do a measurement, you have to press the AVG button so that icon is displayed. Then make your measurement. The display will show the actual wind speed until you stop. Then the speed that is displayed will decrease to some value (probably the average) and hold there for about 5 seconds then begin to decrease down to zero. The only thing the instructions say about this is - "average reading in 15 seconds will be displayed". Despite the lack of detailed instructions on how to use the MAX/MIN and AVG features, I found the wind speed measurements to be quite accurate. I tested the unit several times at different speeds by holding it out of my car window with MAX showing on the display. As I drove, I kept an eye on my speedometer to note the maximum speed I attained. When I stopped and checked the reading, it was right on what my speedometer indicated. At least it was accurate up to a speed if 32 miles per hour, which is the fastest I have tested it so far. The instruction sheet indicates that the speed accuracy is +/- 5%, which appears to be true. The next time I hit the highway, I'll check it out at 65 mph. Also displayed at the bottom is the air temperature, which is switchable between °C and °F. The unit apparently has a wind chill feature that only works when the temperature of the unit goes below 0 degrees C (32 F). Again the instructions are vague on the subject. I had to go back to Amazon's listing of the unit to learn that, when the air temp is below 32F, the temperature reading changes from the actual air temp to the wind chill value. Being in Florida, I don't think I will ever have the opportunity to check it out. I'll leave that up to the poor devils up north. Another feature I like is the switchable backlight. Great for checking wind speeds at night. Finally, the bottom line is that the HoldPeak 866B does what I bought it for - to have an inexpensive hand-held anemometer that will measure wind speeds with some degree of accuracy.

Rock Solid Anemometer
Color: 1Pcs 866B Anemometer
This is a nice and fairly well made Anemometer that I'm glad I purchased. It's easy to use, battery life is really good, accuracy seems good plus very sensitive for a value meter and the screen brightness is plenty for me to easily see the results. I can't really think of any complaints since it's lasted me a while now and has been used well more than a dozen times so far. I primarily use it to test various fans that I have. That way I can have a measurable output to log as data for comparison purposes. That way I will have a general idea of what I need for future fan purposes now that I have data to compare. There are several other air things that this can be used for, but that's what I'm using it for at this time. I want to use it for other purposes in the future and am excited to see how it will pan out. If anything changes for the good or negative, I will update my review accordingly. After many months, it has held up very well and is still going strong, so I'm not sure what to anticipate at this point. Time will tell.

Nice and neat, runs on 2 AAA batteries
Color: 1Pcs 866B Anemometer
This little gizmo works well and is more sensitive than I expected. I was using it to test the airflow of certain filters vs without. While I was testing one without, a small rock flew from the filter and broke all but one of the fan blades. This is no fault of the device but of my own, and I take the blame. I did get the measurements I needed, and will be ordering a replacement here soon. I can still get rough estimates on max though, just takes longer. Only odd setting is the minimum airflow in my opinion. You need air to be moving through already to get an actual reading, which in some circumstances may be difficult If you can't see the screen while testing. Once you stop the flow the minimum starts dropping. Personally I don't need this function, but it is still a nice feature. Comes with a little zip case and an optional strap that screws onto the bottom if the meter if you don't need it to be mounted. Also has an airflow direction arrow on top. Batteries included, 2 AAA. I don't like trying to deal with button cell batteries.

Simple and inexpensive - instructions lacking
Color: 1Pcs 866B Anemometer
I like the simplicity and size of this handheld anemometer. It is easy to setup and use. It seems accurate although it’s hard to gauge without a standardized wind tunnel setup. The instructions and videos, typical of most Chinese made products, are considerably lacking and not well written. Specifically they do not explain the functions or how to use very well. But it was cheap and good enough for my use (measuring air speed coming from fans and HVAC ducts in my house). They should consider hiring a native English speaker to rewrite the manual and narrate the videos.
