What is a pocket barometer?
Barometer is a hand scientific device that measures atmospheric pressure, which can help predict short -term weather changes. Backpackers, tourists and other outdoor enthusiasts often use a pocket barometer to monitor prevailing weather conditions and help plan their trips. Although the traditional pocket barometer would come in the form of a brass pocket barometer with an analog display, many modern pocket barometers are technologically advanced tools with digital readings. The pocket digital barometer often provides information on atmospheric pressure as well as temperature, humidity, factor of wind and ultraviolet (UV) index, measuring ultraviolet radiation, although conventional barometers have been used since the 17th century, pocket barometers began to gain popularity in the 19th century. Advances in technology allowed craftsmen to construct barometers that were smaller than cones barometers and can work without mercury, which may be dangerous to people's health ifThey will not handle them correctly. The traditional pocket barometer is designed to move the barometer indicator clockwise through the dial, indicating high or low atmospheric pressure. Some models of pocket barometers made in the 19th century are valued by antique collectors.
Many backpackers and tourists consider modern pocket barometer to be basic equipment for trip, along with objects such as a pocket compass, map, knife, matches and sunscreen. The pocket barometer can be particularly useful for tourists who map a course in a mountainous area where they could experience numerous changes at altitude. The primary point of view when reading a barometer is that rapidly decreasing atmospheric pressure suggests that the weather conditions are about to turn, from mild and sunny to overcast, rainy or snowy, depending on position and its altitude.
Modern Pocket BarometR is often available in the form of digital watches that, in addition to atmospheric pressure assessment, offers various special features. Digital barometers often include altimeter, devices that measure altitude. Tourists use the altimeter in conjunction with the topographic map to help confirm their placement on the way. Other common features include an alarm that sounds that indicates a sudden decrease in atmospheric pressure and a tool that monitors the tourist speed of output or descent in footsteps per hour. Pocket barometers are available in outdoor stores and from retail dealers of special facilities.
