HP-866B Digital Anemometer,Handheld Wind Speed Meter

An anemometer is essential to nearly any outdoor sporting activity. Especially those that involve RC aircraft. For any model pilot, we check the wind forecast before we set out for a day of flying. And, we periodically check wind conditions while we are out. This device takes the guesswork out of wind speed. This particular anemometer is a very professional grade machine, that can be hand held or tripod mounted (better for ground station operations). The built in thermometer warns of rapid temperature changes (indicating possible storm activity approaching). I like the back lit display for twilight flying. And, the carrying case is great for keeping the device safe from damage during storage and transport.

I really like this device. It is really clear and simple to use. It seems to be very accurate and very responsive to changes in wind speed. I was using it to measure the exhaust speed of the air coming out of the exhaust pipe of one of our helicopters. I got good and consistent reading for the idle exhaust speed. I'm going to buy another one because I still want to measure the downwash velocity at no-lift and at hover.

Le premier appareil reçu s'est avéré défectueux. Il ne s'allumait tout simplement pas. Le vendeur a été ultra réactif. Le second fonctionne parfaitement. Ayant eu l'occasion de tester deux modèles identiques en même temps, ils donnent exactement les mêmes valeurs mesurées, ce qui est rassurant. Petite précision, la mesure max/min et avg (moyenne) ne peut se faire que sur une mesure. Autrement dit, on mesure la valeur max (ou min ou avg) sur un temps donné et non pas les 3 données en même temps. Dans les faits ce mode de fonctionnement est pratique. J'ai apprécié la housse et la dragonne fournie. En revanche comme vous pouvez le constater, la petite notice est truffée d'erreurs. Mais on s'en passe.

Excellent instrument.

Easy to use. Comes with everything you need to use. Very Happy with product.

I have not had the opportunity to site test this unit yet but I received it on time and in an extremely efficient packaging ready to go after installing the 2 batteries that were included. The fan is very well balanced and sensitive to even the slightest breeze to the point where Wind speed and ground speed correlated exactly when compared with a GPS just walking. It comes with a nice case and easy to follow instructions. I have no doubt this unit will meet my requirements. Only improvement I might suggest would be a way to connect to a computer to input the data in real time. Next model.

A very good device for hiking

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.
