The handheld anemometer is a handy tool for any person who is into weather watching. The anemometer was first developed during the 15th century and has been improved since then. The term “anemometer” comes from the Greek word “anemos” which in English means “wind”.
The History of Anemometers
The first anemometers appeared in Italy and in Northern Europe before spreading to the Americas. They were very simple and ingeniously designed. It composed of a single flat disc which would shake in accordance to the winds motion. By looking at the inclination of the disc, the people could determine the degree of the wind pressure. By mid 19th century, more sophisticated anemometers were being used as cups were attached to the ends of a wind vane. When wind rose it would be caught by the cups making the vane turn. The number revolutions of the vane were recorded for readings. This kind of anemometer is still being used today. A similar version of this type spins like a wind mill (vertically) instead of the traditional vertical spinning.
The anemometers if today use the incorporate the latest wind reading technology. They no longer rely on wind alone to give them basis for measuring it (wind) but also use different kinds of high-tech methods such as the measurement of thermal energy, detection of particles through laser beams and the movement of sound waves.
What can an anemometer do?
The anemometer is basically a device used to measure the speed of wind. Modern anemometers not only measure wind speed but also different aspects of the wind such as: humidity, temperature and pressure. Anemometers are usually used in weather stations for meteorological purposes. There are five types of anemometers:
- Hot Wire Anemometer – Sonic Anemometer – Laser Doppler Anemometer – Windmill Anemometer – Cup Anemometer
The Handheld Anemometer
Also known as a personal anemometer, the handheld anemometer is not a large device measuring only a few inches in length and width. It is able to measure wind accurately, usually within 5% of the exact reading. Almost all handheld anemometers are able to do three things:
- Easily display wind readings, – Measures wind speed (measures up to 100mph easily) in mph, km/h, m/s or Knots – Read wind chill and temperature in Fahrenheit and Celsius
Depending on the brand of the handheld anemometer that you buy, manufacturers are now being creative with their additional features. Some have waterproof cases and can even float on water. Others can measure wind using the Beufort Scale while others are made to be very durable that they will survive a drop of several feet.
Uses of the Handheld Anemometer
People who need to be knowledgeable about the weather to be able to perform better, whether in their job or in their hobbies, can benefit from using a personal anemometer. Examples of these people are: kite flyers, engineers, climbers and wind surfers.
Both professionals and amateurs can benefit from using a handheld anemometer. Since it is handy weather watchers can easily make their own weather forecasts confidently.
