The Aoputtriver AP-816B Digital Anemometer (herinafter, simply called an anemometer) is an instrument designed to measure wind speed. It is also equipped with an onboard thermometer that reads in °F and °C.

It benefits such people as sailors, surfers, R/C aircraft pilots, or anybody who needs to know the wind speed for any reason.

Wind velocity can be measured in a number of different units, such as mph (miles per hour), kph (kilometres per hour), m/s (metres per second), ft/min (feet per minute), knots (nautical miles per hour), and the Beaufort scale. It also has maximum hold, minimum hold, and average wind speed functions; and can even display the chill factor under the right conditions!

SIZE

To use your shiny new anemometer, install a CR2032 lithium coin cell (that you need to furnish yourself), and THEN you can go measure that wind speed before you launch that equally new and spiffy $2,458.77 R/C model airplane.

To turn the anemometer on, press and hold the button labelled, "MODE" located over the display and to the left. Hold the button down for approx. 1 second (or until the display turns on), and then release it. The green LED display backlighting will come on, and stay on for 5 seconds before turning off. If you need the backlight on again, briefly pressing any of the buttons & then releasing them turns the backlight on for 5 more seconds.

Hold the anemometer a foot or more away from your body, positioning the product so that the wind strikes its impeller blades at a 90° angle -- in other words, hold it so the wind blows directly on either the front or back of the product. If you have the anemometer hanging around your neck, you need only bring it to the side of your body as far as the neck lanyard allows; no need to remove it from around your neck.

After a few seconds, look at the display and you'll see the wind speed (in whichever units of measure that you have the anemometer set to). If you have it set to maximum, minimum, or average hold, the display will "remember" these values and continue to display them. To reset the anemometer to zero, just turn it off and back on.

Because the wind speed display resets when the unit is powered off, this might not be the best anemometer for you if you're a model aircraft pilot.

If the ambient temperature is 0°C (32°F) or lower, this anemometer will display the wind chill factor as well.

To neutralise the product, simlutaneously press & hold down the the MODE and SET buttons for ~5 seconds, then release them.

To change the wind speed units of measure, turn the product on first. Press & hold down the MODE button for 5 seconds; release it when the display goes almost completely blank. Pressing & releasing the SET button cycles through the wind speed units; press & release the MODE button to lock in your selection.

To change the temperature from °C to °F (or vice versa), turn the anemometer on. Press and release the button in the center that has °C/°F silkscreened under it.

The anemometer will "remember" these settings until you have to change the battery.
Unlike two other anemometers I've tested however, the displayed wind speed value is NOT retained when the unit is powered-off -- either manually or automatically.

To change the battery in your anemometer, turn it face-down, and look for a circular hatch. Using a coin like a quarter (a US 25¢ coin), insert the coin into the slot that you see in the hatch, and give it ¼ of a turn counterclockwise (or "anticlockwise" if you prefer). Remove the hatch cover, throw it into the dustbin (garbage can), tie off the bin liner (plastic garbage bag), carry it to outdoor wheelie bin (wheeled garbage can), throw it in, slam the lid down, and wait patiently for garbage day so that the dustman (garbage man) empties the wheelie bin into his dustcart (garbage truck)...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Remove the tired old CR2032 lithium coin cell, and dispose of it properly (your regular household rubbish bin is an appropriate disposal location; to the best of my knowledge, lithium cells & batteries are not yet recyclable).

Install a new CR2032 cell, button-end (negative) facing down, into the battery chamber. Be certain that it is seated in there somewhat straight; if it went in there crooked, tip the cell out and try again.

Place the hatch back on (ensuring that the O-ring doesn't fall off and become pinched between the hatch and the product's body) , and use your quarter to turn it clockwiwse ¼ of a turn until it stops.

Aren't you glad that you didn't huck that battery hatch into the dustbin now?

This is a digital anemometer, not a flashlight meant to be thrashed, trashed, and abused. So I won't try to drown it in the toilet tank, bash it against a steel rod or against the concrete floor of a carport in effort to try and expose the bare Metalmarineangemon - er - the bare Metaltrailmon - um that's not it either...the bare Metalsusanoomon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again!

- now I'm just making {vulgar term for feces} up!!!), let my mother's big dog's ghost, her kitties, my kitty or my sister's kitty cat piddle (uranate) on it, hose it down with my mother's gun, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (now I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analyses, or perform other indecencies on it that a flashlight might have to have performed on it. Therefore, this section of the anemometer's web page will seem a bit more bare than this section of the web page on a page about a flashlight.

TEST NOTES:
Test unit was purchased on Ebay on 07-31-21 and was received on the afternoon of 02-06-18.

I purchased it for the primary purpose of measuring wind speed for flying drones, helicopters, and other model aircraft; my old anemometer petered out, so this is one of two replacements.

Product was received in a timely fashion, but was dead on arrival (DOA); therefore the dreadful, "

" icon will be appended to its listings on this website at once.

I've ordered new batteries; I'll give this product another chance immediately upon receipt.

UPDATE: 08-10-21
The fault lies with the fact that this product requires a significantly higher terminal voltage than the other two anemometers that I've used; once a new CR2032 lithium coin cell was installed, the product powered up and functioned properly!

PROS:
The price is most DEFINITELY right!
Compact size for easy storage & transport
Unit "remembers" wind speed units when powered off; however changing the battery will reset this parameter
