1, the use of the physical principle of the design of this product:
tourbillon4uwatch< p > SUUNTO watch manual (1) due to gravity atmospheric pressure. (2) the higher, per unit area under the air column is short,
quartzsale.com, the atmospheric pressure is small. tourbillon4uwatch,< p > (2) and a pneumatic changes result in changes in the weather, this change will this altimeter dial. The device can accurately measure the height (absolute height) through a transmission device of high precision display, the height difference,

no batteries and chargers.
3, according to the pressure value to predict the future changes in the weather, let your
be prepared against want.
4, easy to carry, the design is reasonable,www.chronoonhere.com, can give you the outdoor sports bring easy and convenient.
two, functional description of
absolute height. In the initial altimeter used before or after purchase, to adjust to the local digital altimeter actual altitude. At this time please note: please refer to the map on the value of the calibration altitude. In addition, the change in air pressure change and the weather will continue to affect the table above sea level height therefore, it is necessary in the process in climbing or walking continuously in the reference height; the relative height measurement: in the process of climbing or traveling, if you need to measure the height value please according to the following two steps; (1) before the high degree meter is initialized, pointer at 0 scale (2) in the process of moving or at the end of the measured height is the height value of tourbillon4uwatch
forecasts that the weather trend is usually in the case of a sharp pressure value.
