Handheld Anemometer

I use it all the time to measure wind speeds before I spray for mosquitos. Handly little anemometer. Battery lasts a long time. Has worked just fine for almost 2 years now.

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.

It arrived in good condition. The generator has to be fragile, but mine seemed to work ok. My concern is longer term accuracy, due to dust and mishandling slowing the rotor. knowing my own habits of trouble protecting sensitive test equipment, I ditched the zipper bag and keep it in a ziplock in its cardboard box. I don't want anything to affect or slow it's rotor speed.

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.

Lightweight; worked great. Keeping it on my boat for wind checks and speed checks

Excellent product. Worked as expected.

This thing is the bomb. I bought it to replace an ancient, manual (Dwyer) gauge that was just showing its age, poor thing. And it topped out at too light a wind to measure stuff like a full gale with gusts or anything over that. I wasn't sure I wanted this . . . Sometimes digital stuff and I just don't get along. . . . But, the minute I got this I went outside and started playing with it in the gusty wind that day to see if I could manage the buttons (that sounds silly, but sometimes too many functions on too few buttons is NOT a plus for moi). It was SO easy. And actually a lot of fun to goof around with. I'm so incredibly happy with this little gizmo. I'm thinking of giving one to a friend for a birthday gift.

This review is for the HoldPeak HP-866B_WM. I would give it 5 star review except that it reports a bad windspeed value when in mph. If seller corrects this issue I will update this review. Except for this I am very pleased with my purchase. UPDATE: 10/8/2017. Manufacturer sent me second HP-866B_WM, and it has the same problem with windspeed in MPH. When I told them this, they said they would send the unit back to engineering to fix. In brief: PRO: Lots of good measurements. Light, well constructed, and easy to use. CON: (1) MPH reading is not correct. (2) Difficult to remove battery cover, requires screwdriver. (3) Unit forgets my last selections when powered off. WORK-AROUND: When I want MPH, I use the approximation that 1 meter/second is about 2 miles/hour, so I double the m/s airspeed reading. Appearance The unit I received looks exactly as pictured, with 6 buttons, blue rubberized bumper on left and right. Across the top: red power on/off, Wind, Baro. Across the bottom: Mode, T/RH, Alt. On backside is the battery cover and a rubber cover over an open rectangular hole. This is where the USB connector would be if this unit had a USB connector (it doesn't have one). Also the unit serial number (mine starts with 20170223 which looks like a datecode probably for the date of manufacture February 23, 2017. On the bottom is a metal screw spot where you can screw in either a tripod or the supplied hand strap. Size, weight Unit measures: width that varies from approximately 2.5" (6.3cm) where you hold it to approx. 3 3/8" (8.3cm) across the widest spot on top. Length is approx. 6 5/8" (16.7cm) top to bottom not counting the strap and its screw. Depth of unit is approx. 1.5" (3.7cm) at deepest spot (by the fan). Unit weighs approx. 5.56oz (157.5g) with batteries and strap attached. Power Unit requires 2 AAA batteries, and two come with the unit. Note that the battery cover is screwed in with two Phillips type screws and the cover is difficult to remove. This might be to provide some rain resistance. Windspeed The unit reports windspeed in meters/second (m/s), Kilometers/hour (Km/h), feet/minute (ft/min), knots, and miles per hour (mph). I know that my unit's windspeed is reported incorrectly in mph because: weather report says winds about 3 mph; outside, I see windspeed of 5 Km/h but when switch to mph I see 0.3 mph. Maybe it's a decimal point issue? I'm not sure, so I'm viewing windspeed in meters/second and multiplying by 2 to get a close approximation to miles/hour. Unit also reports: Barometric pressure in inches mercury in inHg and hpa mbar. Temperature (Centigrade and Fahrenheit), relative humidity, and dew point (Centigrade and Fahrenheit). Altitude in meters and feet. I'm not sure how accurate the altitude is so it might be best to use as a relative measure. The top display in large letters shows either Windspeed or Barometric pressure. The lower display in smaller letters can display temperature, relative humidity, dew point or altitude along with windspeed or barometric pressure. The Mode button only has an effect when you are displaying windspeed, and switches the mode from normal (instantaneous windspeed), Max, Min, and Avg (average). Holding down the Mode button for about 3 seconds turns on or off a very nice screen backlight. When you turn the unit on, it starts with windspeed in m/s and temperature in Centigrade regardless of what display you'd set it to earlier.

Good one

Funcionan perfectos

Fait très bien le job avec juste les fonctions basiques qu'il faut + un éclairage d'écran inclus. La précision semble au rendez vous (0,1m/s de précision)

Das Anemometer ist ein praktisches Gerät zur Bestimmung der Windgeschwindigkeit. Funktion und Art der Anzeige sind fast selbstbeschreibend. Ich finde es hilfreich auch zu Hause die Windgeschwindigkeit bestimmen zu können.

He usado este producto para calcular el aire extraído de una habitación por un tubo. He podido medir a qué velocidad circula (0,1 m/s) y esto nos permite calcular el caudal. Echo a faltar que no cambie el signo de la medición, cuando cambia el sentido del aire. Por lo demás es exactamente lo que buscaba.
