The Vortex Pro-1200 "Plus" anemometer is an affordable way to provide you with accurate wind speed in places where AC power may not be available.

The jack connection and flexible wire make the unit more suitable for mobile use than the standard Pole Mount Anemometer, whose exterior grade wire is more rigid, and which does not include a connector.

You can mount this anemometer to your own pole or roof bracket, bring the wire in through a window or some other hole, and stick the display on the glass, a window, or anywhere you want.
Connect the display and Voila!

The Vortex Pro-1200 Plus portable anemometer display is a high quality, Sigma Sport bicycle computer. Speed range is approx. 5 to around 150 mph, although the calibration has only been verified from 5 to 50 - we did not find a wind tunnel with 150 mph calibration facilities! Check out the specification tab for details. Battery life is around 1,000 hours of continuous use. Some anemometers we tested on our home lasted for well over a year on the original batteries!

SENSOR TYPE	3-Cup rotor Reed switch/magnet provide 1 pulse per rotation.
ROTOR DIAMETER	approx. 6 in (150 mm)
SPEED RANGE	approx. 3 mph to 125+ mph (~5 kph to over 200 kph)
MOUNTING BRACKET	Anemometer is supplied with an aluminum mounting bracket with 2 holes for screws. Designed to be mounted on top of a pole or bracket. Custom brackets available up request (offset, for example)
WIRE	Standard length is 25 feet (8m) Shorter lengths available on request Wire can be extended using any 1/8" jack audio cables
DISPLAY	LCD Digital Display on anemometer is a Sigma Sport Model BC-1200 bicycle computer. Dual Display simutaneously shows CURRENT SPEED (top display)plus: MAX, AVERAGE, KM/MILES, or several other (bicycle-related) functions. Select mph or km/h (knots too if you wish - see Owners Instructions for details) Water-resistant (not waterproof). Provided with high strength self-adhesive Velcro pads for mounting the display
POWER	CR2032 Coin Battery located in the display, not the rotor/head. Battery life 1 to 3 years of intermittent, occasional use. A few months to a year of continuous use, depending on wind conditions and mode of use (Display goes to low power mode when the wind speed drops to zero, or if removed from the bracket when not in use)
SPEED RESOLUTION	Top Anemometer Display (Current Speed): 0.5 mph Bottom Anemometer Display (Max, Average, etc.): 0.01 mph
DIGIT SIZE	Top Anemometer Display (Current Speed): 10mm (approx. 1/2") Bottom Anemometer Display (Max, Average, etc.): 5mm (approx. 1/4")
UPDATE RATE	Approximately 1Hz (1 second)
ACCURACY	A few tenths of a mph from 4 to 10 mph +/-4% from 10 to 50 mph estimated within 4% above 50 mph click HERE for a calibration chart
	IMPORTANT NOTE ABOUT AVERAGE WIND SPEED: Since bicyclists do not want their average speed to be diminished when they come to a stop, the computer will only record and average when the wind is blowing. It stops recording below approximately 1 mph. That means that if the wind blows for 2 hours at 20 mph and 2 hours at zero, the average shown will be 20, not 10! Please keep this in mind for your desired use of the Vortex anemometer. WORKAROUND : if you want to know the real average wind speed - even with spells near zero, do the following: reset the computer, note the time. When desired, simply divide the total number of wind "miles" on the display by the number of hours since reset.

Dan is a Storm Chaser with a great web site. Click here to see it.	"Went fishing this morning and could not pass up this shot. Great sunrise. Your system is much more sensitive to the slightest breeze, even in the morning mist, an occasional spin would be seen. As for the degree of error, it seems to be quite close to the speed while traveling down the road in my Suburban. Will send a photo when I get that also. Right know I have my Kayak on top with all the other gear. Well, have to run." John Mercer Co. Pa. N.W.S. Storm Spotter/Chaser
Chris and Dave are weather enthusiasts using our anemometers and are some of Inspeed's biggest fans - thanks guys!	OK, so you want to mount the Vortex anemometer on your bike? Go right ahead!!
The Inspeed Vortex anemometer was used at the March, 2005 FIS-Sponsored Speed Skiing Event in British Columbia. Crosswinds can be hazardous to your health when you are skiing at 100 mph!!	The Vortex anemometer is great for student projects!
Customer email: "wanted to let you know that I have been very impressed with your Anemometer. We use it on our sailboat. I have had it for over a year now and it is just as accurate as the day it arrived. Just wanted to say thanks for creating an excellent product and offering it at a reasonable price. Great job! " Jamie Sibley http://www.flying-cloud.org	Customer email: "I am in very great admiration of your product, I just recieved mine over the weekend and used it on a HAZ-Mat incident Monday. Do you need a rep. in the Chicago land area? I belong to an emergency managment group and these would be great in a HAZ-Mat truck and for the local fire departments, I plan to spread the word on them for you. I bought mine for storm work, but realized the importance of them for HAZ-Mat as well. Please let me know, I'd be glad to help sell your product. Thank You. " Dan
