Description

Visit the Store A good helper in CFM calculation HOLDPEAK Ltd. is a high-tech enterprises which was established in 1998 and concentrate on research, development, production manufacture and sales. After years of development, "HOLDPEAK" brand plays an important part in the global measurement industry. We will continue to concentrate on providing more convenient, more accurate and securer digital measurement instrument for global users. This wind speed meter detects very low airflow with high sensitivity—making it a reliable helper for HVAC installations, duct vents, and precise CFM calculations. We calibrate every sensor in our own R&D lab. No shortcuts. No cheap parts. Built for the work you do every day. When accuracy matters, trust the brand that's been getting it right since 1998. A handy helper for both fun and work! What can I do with this HP-866B anemometer? It measures wind speed and wind temperature. Use it for outdoor activities like drone flying, shooting, sailing — or for HVAC work like checking duct airflow, testing heating/cooling efficiency, adjusting vents, and solving collector problems. Can this anemometer calculate CFM directly? This anemometer measures air velocity (ft/min), not CFM directly — because CFM also depends on your duct's area. Just measure your duct's area and multiply it by the wind speed reading to get CFM. Formula: CFM(Q) = Wind Speed(V)× Duct Area (A). What are the key specifications of the anemometer? The HP-866B handheld anemometer measures airflow velocity (59–5905 ft/min, ±5% accuracy) and wind temperature (14°F–113°F, ±3.6°F accuracy). Does this wind meter show the room temperature? This digital anemometer shows the temperature of the wind passing over the sensor — that's the "wind temperature," not the ambient temperature. It may vary from the actual room temperature. Is this anemometer portable? What are its dimensions and weight? Yes! The anemometer weighs just 5.4 oz and measures 6.5 x 3.4 x 1.5 inches — compact and lightweight enough to toss in your backpack, tool bag, or even a large pocket. Perfect for taking on outdoor adventures or HVAC jobs. Handheld Anemometer Bluetooth Anemometer Weather Meter Anemometer with USB Mini Anemometer Cup Anemometer Heat Stress Wind Meter

  • 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. ... show more

  • 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. ... show more

  • 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. ... show more

  • 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. ... show more

  • 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. ... show more

  • 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. ... show more
