Skywatch® Wind
Pionnier dans le domaine des anémomètres portatifs, JDC Electronic concentre son savoir-faire sur le développement d’anémomètres de qualité depuis 1984 avec sa marque Skywatch, réunissant deux mots d’ordre : simplicité & efficacité.
La Skywatch® Wind mesure la vitesse du vent, la température de l’air et le refroidissement éolien de manière rapide et précise. Assez petit pour être emporté partout, insensible à la poussière et aux chocs avec une hélice remplaçable par l’utilisateur, le dernier né de la famille JDC est conçu et fabriqué en Suisse.

Skywatch® Eole
Skywatch Eole is an anemometer with a large 54 mm propeller that accurately measures wind strength regardless of direction. The Skywatch Eole is powered by two replaceable LR6 batteries. The display is accurate to one tenth of a unit up to 99.9, then to the nearest unit. The aluminium base gives the device great strength, and the 1/4″ thread on the underside of the device allows it to be mounted on a photo tripod.
A larger, more robust anemometer, the Eole has a multi-directional propeller for precise measurement without the need to be perfectly aligned with the wind. It's the ideal companion for kit-surfers and sailors.
Mounted on a tripod, you can constantly check the current state of the surrounding weather conditions.
The Eole is an unsinkable device, so it can fall into the water without disappearing into the abyss, and its backlighting means it can be used even when daylight is fading.

Dust may have infiltrated and prevented the unit from working properly. Rinse your Eole under clear water quickly, holding the appliance horizontally and passing the propeller under the stream of water. This will prevent dust from accumulating on the propeller and shaft.

To enter configuration mode on your device, simply press the . When you press the If there has been a change, the system validates the setting, otherwise it moves on to the next setting. To change the settings, use the and .
The selectable units are: knots, km/h, mph, m/s, fps and bft. To change the units, see the explanations under "how to configure my deviceOnce the unit has been selected, it will remain displayed in the top right-hand corner. When no unit is displayed, the device is in Beaufort mode.
Selectable units are : °C, °F, temperature felt (in °C or F°). To change the units, see the explanations under "how to configure my device.
Il permet de vous donner une moyenne de vent en fonction d’un intervalle défini. Réglage du temps de la moyenne : Les temps sélectionnables sont : — (pondération), 3’’, 6’’, 12’’, 30’’, 1’, 6’, 30’, 1:00’, 6:00’, 12:00’, 24:00’ ou Timer (un petit chronomètre apparaît sur la droite lorsque le mode Timer est activé : 
). Timer mode is used to measure the average over a set period of time between a start (press ) and a stop (press ), this time is displayed on the bottom line. This Timer also allows you to use the LapTime function (press the symbol flashes). The button can also be used to zero the timer. It works in the same way as a standard stopwatch.
Les affichages sélectionnables sont : —, MIN, AV, MAX. Lorsqu’on sélectionne AV, il s’agit de la moyenne pour la température et pour le vent. L’affichage des valeurs moyennes se fait toujours simultanément pour le vent (au milieu) et pour la température (en bas). Les autres modes (—, MIN, MAX) concernent uniquement la température. Le réglage de l’affichage n’est pas disponible si l’unité sélectionnée est la température ressentie °F ou °C.
Important The cap must be removed from the instrument to allow the propeller to rotate. The propeller provides maximum sensitivity in the vertical position (thanks to its magnetic levitation) and optimum accuracy when its axis of rotation is perpendicular to the wind direction.
The instantaneous wind speed is shown at the top of the display, with the maximum wind speed in the middle. The maximum wind speed is displayed in the centre. This is the maximum value measured over the average time. The value is set to zero when the memory is reset. Average wind speed (bottom of digital display) The average value is displayed on the 3rd line, and is the average value calculated over the pre-selected time. Only for the Meteos: the average does not work if the device is in a perceived temperature mode.
As you probably know, low temperatures are dangerous for the human body. But did you know that the wind has a major influence on the temperatures your body actually feels? For example, an ambient temperature of 0°C and a wind speed of 30 km/h have the same effect as a temperature of -13°C! The result of calculating the effect of wind on temperature is called the "felt temperature". Whether you're at sea, in the mountains, hiking or cycling, the Skywatch Meteos gives you an instant indication of the temperature your body is feeling, warning you of frostbite and hypothermia.
To reset your values, simply press the and for about 3 seconds.
As this anemometer is not designed to act as a datalogger, it is not possible to record or export the measurements taken.
In these two modes, this is the minimum or maximum value measured over the averaging time. The value is reset to zero when the memory is RESET. These values are not given for the temperature felt by the body.
The device is waterproof and weatherproof, but only needs to be submerged for a short time.
Yes, there is a 1/4" thread on the base of the camera for mounting on a tripod.
What is the power supply and autonomy of my Skywatch® Eole/ Meteos? Your anemometer is powered by 2 x 1.5V (AA) batteries. Battery life is a minimum of 3 years with occasional use of the lighting.
To change the batteries in your device, simply unscrew the three screws on the metal plate (base).
Your appliance is switched off by pressing the on/off button for 2 seconds ( ). There is no automatic stop.
The SKYWATCH speed measurement principle® Eole Meteos est basé sur la détection du champ magnétique tournant produit par l’hélice. Si l’appareil est en présence d’un fort champ magnétique produit par un transformateur ou un moteur, il se peut que l’instrument indique des valeurs non désirées, en l’absence de rotation de l’hélice.
If your propeller is damaged or the shaft broken, you can change it yourself. See the following PDF:
Our anemometers cannot be calibrated independently and are checked in our workshops before being released for sale.
See the relevant question in the general presentation of the hand-held anemometer page (at the top of the page).
Skywatch® Meteos
Whether you're at sea, in the mountains, on a walk or on an expedition, the Skywatch Meteos is there to tell you instantly the temperature or the actual temperature felt by your body when the wind blows.
Skywatch Meteos is an anemometer-thermometer that accurately measures wind strength regardless of direction. The Skywatch Meteos is powered by two replaceable LR6 batteries. The display is accurate to one tenth of a unit up to 99.9, then to the nearest unit. A thread on the underside of the device allows it to be mounted on a photo tripod.
Measuring the temperature you feel: As you know, low temperatures are dangerous for the human body. But did you know that the wind has a major influence on the actual temperatures felt by your body? Take the Skywatch Meteos with you wherever you go and you'll instantly know how your body feels, so you can avoid the risk of frostbite and hypothermia.
Calculation: The temperature felt is calculated by taking into account the ambient temperature and the wind speed. In windy conditions, it gives an indication of heat loss if the temperature is below 37°C and heat gain if the temperature is above 37°C.
For example: an ambient temperature of 0°C and a wind of 30 km/h have the same effect on your body as a temperature of -7.8°C!
