There was once a time when taking someone’s temperature involved warming up a glass tube which contained Mercury and then placing it carefully under the tongue for several minutes until the Mercury rose to the indicated temperature number.
The number was given in Celsius however and was rather complicated to read not to mention the amount of time in which it took not only for the preparation of the thermometer but also the total process all together was ridiculous.
It was not until many years later that people discovered the dangers in the substance known as Mercury. Just one small crack in the glass tube could send someone into a fatal attack of the blood stream. After this huge discovery, came the invention of the safer, easier to use digital thermometer.
The battery powered digital thermometer is not only easier to use but, it also does not have a single drop of mercury in it so it is safe to use. It works by electronically taking the persons temperature through a highly sensitive board of circuits in the tip which detect heat when in contact with it. The temperature is then displayed digitally on a small LCD screen so that it is easy to read. Unlike with the old mercury glass tube though, the digital thermometer is available in many types from baby pacifiers to ear thermometers and even medical grade forehead scanners that work by infrared. These thermometers were a huge step for technology and the world too.
With baby pacifier thermometers, a parent could take their infants temperature by simply getting them to do what they love to do already; suck on a pacifier. Within minutes, a parent could have their infant’s temperature with no fuss or stress to either party. Even better however, when the invention of the no-touch thermometer was released. This thermometer put digital in a class by itself.
Used in many pediatric hospitals, the touch-less digital thermometer charges on a base and is used by simply scanning the forehead. Infrared censors pick up the temperature within seconds and with no requirements to even touch the person. This type of digital infrared technology thermometers are also used in an ear type in which the temperature is taken by inserting the tip into the ear for just a second.
You do not need to get worried that from where you can buy one. Anyone can easily buy one from area medical or general store. These thermometers are available at reasonable price. However, if you find it difficult to go to any store, you can buy one online. Just select the appropriate one and stay safe.
There is no doubt that the thermometer has come a long way as has technology. Since the first discovery of the dangers of Mercury until the first release of the digital thermometer, people were in a constant state of fear to use the glass tubes. Now however, people are provided with a safe, durable and convenient way to take their loved ones temperature free, from these worries.
